Yes, I can confirm fireworks only need a small mistake to be dangerous. Back in July 2021, we were celebrating Fourth of July in our neighborhood. My family had only brought smaller fireworks, but one of our neighbors and his friends had lit a big rocket in their backyard. Just after lighting the rocket, they noticed the plastic wrapper on the rocket hadn’t been removed. So, one of them went to go take it off, and knocked it sideways. The rocket launched, and exploded right in the middle of the neighborhood. My family scattered. Everyone had a fireball less than half a foot from them, one of the fireballs landed on the neighbors’ Shelby GT350, but fortunately, no one was hurt. After watching this I can see how much worse that could’ve gone
here in germany, every new year's eve has massive semi-rioting crowds using big firecrackers and horizontally launched rockets as weapons against each other and the also always present riot police. it seems to not produce very many injuries, mostly because the vast majority of fireworks are legally purchased and regulated to only use black powder for the explosive charge, which explodes so softly that a firework has to be in direct contact with a body part to cause serious injuries. illegally imported flash powder firecrackers from poland or the czech republic are also poular though, and those have much more injury potential.
I never read those long comments .

Wow! That last story was refreshingly admirable. I was waiting to hear "and William ignored her warning", but the fact that William listened to Diane was great to hear. Thanks for this one!!
Amen to that! So many people wouldn't do so because of pride.
Holy snapchat imagine building à skyscraper just for it to be threatened by your neighbor's because they chose formidable over function?
Its à good thing he solved that issue, or else he would have been sued by thousands of people for billions of dollars, and thats not including damage costs: it would have been for loss of life and injuries ( doctors in the US aren't cheap)
Yeah it is an example made into textbooks. However, the root cause was those legs were supposedly be around corners instead of centers when it was designed. However, there was a building beneath it, so they move those legs to the center instead. However, moving them to center created the corner problem, as mentioned in the video.

Omg that last one! Not only was William cool about having someone tell him his design had a flaw, he accepted it and worked on how to fix it, without causing panic amongst people unnecessarily. Good for him, he really stepped up. And good for the lady too, who notified him of the issue instead of just thinking “not my problem”
Higher intelligence is displayed, when considering criticism, as practical, and a check on the work?
Really well done to Diane for spotting it and well done to William for listening and fixing . Too many times pride gets in the way but cudos to these two
first!
@@sebastiaanvanderpauw4594 And? You're not getting an award for that.
I'm really glad William LeMessurier actually listened to Diane and actually spent the time, money, and effort to correct his mistake. So many architects get too prideful of their work, and just ignore the warnings of others, and just let their work be.

Props to the designer of the building for making sure that the building was safe and not assuming he was right. If more people looked into structural issues, many disasters could be avoided.
We need more like him
I totally agree. He was able to recognize he made a mistake and instead of making excuses he made changes
Yeah, one Korean fella 🇰🇷 in the 90s was negligent. Once he was convinced his department store was giving way, decided to leave without alerting customers and staff for fear of revenue loss, then hundreds died, and another over 1000 injured.
One of the rare times when an important man listened to a woman.
take surfside for example the question on that is less why did it
collapse but more how had did it ever stand
It should be noted that Citicorp Center was designed with "legs" not just for the sake of being unique, but because a church owned the corner of the site and refused to relocate. So the skyscraper's developers worked out an agreement where they'd put their building *above* the church, with columns to hold it up.
Wow just wow I mean I can understand not wanting to move your place of worship but this could've caused a huge failure that would've costed hundreds of lives if it wasn't for the quick thinking of engineers
Great Church, Why Care about OTHERS.
@@Dovah_Slayeroh I see
Um..the “legs” design was SOLELY to build around the Church.
@@Dovah_SlayerQUICK thinking? It was YEARS LATER that the mistake was discovered!!!
The stadium collapse was caused by a resonance of the structure, much like the infamous Tacoma Narrows bridge collapse. This concept wasn’t widely understood in all structural design. It’s understandable that a resonant excitation, people jumping in unison, in the design of a stadium structure, especially in the 1930’s. Not even an earthquake excitation would be expected to excite vertical vibration mode.
15:54 it's actually surprising how much a single lit bud can cause a lot of trouble. In my previous job, we had a "big tool room" where a lot of people used to go for smoke breaks since it had large doors leading outside. One day i was left in our building to prepare tools and materials for a job , when I noticed smoke in the corridor. I looked through all the rooms only open the tool room and see it filled to the brim and fire somewhere.
After telling others of the fire and putting it down, we realised that it was a trashcan someone dropped a still lit cigarette into it and things could have been much worse. Trashcan stood next to jerry cans filled with benzene and diesel as well as propane tanks and if it wasn't for the can melting away from jerry cans and us noticing fire fairly early, things could have gone much worse
Boy, you sure dodged a bullet there! Did you buy a lottery ticket afterwards, from how lucky you were?
@@makutamon Not at the time for sure
Wow, that sure was lucky. I've heard benzene fires are hard to extinguish, and that you can't use water for it at all.
@@amberkat8147 Yeah, similarly to burning oil, trying to extinguish those with water only makes it spread out faster as water literally boils and throws it everywhere in the process.
Oil and benzene/petrol/gasoline you can only fight using powder filled extinguishers to create this hardened layer that suffocates fire.

There's more to the Citicorp building story. If the building had been constructed as LeMessurier (pronounced "le-measure") had specified, it would likely have been adequate to resist "quartering winds", but an on-site change to the construction of the diagonal braces that directed load to the legs of the building - from through-welding to bolts - significantly weakened the structure. LeMessurier discovered that on his own, once he was prompted to start thinking about quartering winds.
The timing as reported here is also very sloppy. It was only toward the very end of the refit of the building - which could be done at night, with minimal disruption - that the hurricane showed up, and it veered away from the city, in any case. LeMessurier took his time to mobilize the people, resources, and plans needed to carry out the refit responsibly. It's really a model of how professional engineers should behave.
Also, fun fact: the building was one of the first to feature a tuned mass damper, a huge block of concrete on bearings at the top of the building, which served to reduce sway . . . but which would have increased damage to the surrounding area had the structure failed.
Also also, at the time of the building's construction, New York City building code did not have any specifications regarding quartering winds, which just goes to show that building codes are often inadequate on their own.

The DeHavilland Comet window theory has been disproven. The issue was with the structural integrity of the airframe itself and the overestimation of the material resistance lifespan (i.e., how many pressurization cycles it could withstand before failing).
True.
Just about to post the same thing
The real culprit was microcracks that formed because the structural pieces of the fuselage were riveted together instead of drilled and screwd. Seconds from disaster series does explain it quite well.
*New York has a blackout*
*Everyone goes pandemonium and starts looting everywhere*
That’s about the correct civilised response you can get from the people apparently. That will definitely resolve your power cut.
It makes me so mad for some reason when people keep blaming the windows

I was absolutely livid when the El Dorado fire happened. I went home on leave while still serving the military after being away from family for almost 2 years. Literally the day after I arrived home, I woke up to tinted orange skies and was forced to cancel all plans I had the following few days due to all the smoke and restricted outings because of covid, forcing me to stay home until my flight back 10 days later. Stuff like this are the reasons why we can't have nice things.
And all for something as ridiculous & pointless as a gender reveal party.

A correction on the Comet airplane one- yes, those square corners may have been where it was always going to break, but planes broke so quickly because at the time they didn't have any experience with flying that high so the metal was just too thin. That thin metal flexed with every flight cycle- every cycle of depressurization and repressurization- and was bound to give out.
Also while the windows were squared they had round corners
The windows as the cause for the loss of the Comet airliners has been debunked so many times.
Agreed with all the comments. The issue wasn't the 'square' windows (they had rounded corners). Another factor was the way DH bonded the metal, it just wasn't strong enough, and lead to metal fatigue too, at the joins.
Correction on titanic, it was an ocean liner, not a cruise ship
The first N1 explosion didn't cause the Soviets to lose the moon race either. They launched 4 of them and all of them failed only one due to a bolt coming loose and being sucked into the engines. It had many of the same problems the new spacex craft has like having a lot of engines that all have to work in sync. I think the N1 had a 30 different engines of 2 different types and most of them needed to work in sync to have a successful launch. They also couldn't test the rocket in a standing position like the USA could due to a smaller budget.
The blackout in NYC in 77 also Happened in August 03... to the entire North East Coast. One of the power plants in Niagara falls around Ontario Canada went down and created a chain reaction. It lasted a few days.

A small change to the building plans for a pedestrian catwalk in the lobby of the Hyatt Regency Hotel in Kansas City led to its collapse during a party in the early 80's. There were something like 180 fatalities. It wasn't faulty materials, or improper methods. It was simply a small change made after the plans were completed. As a result of 1long bolt changing to 2 short bolts, the weight distribution went from being shared across multiple levels to being entirely put on one level. A high school student doing a small experiment could have determined the logic behind the change being catastrophic, but it was changed for 1 stupid reason. Its easier to carry 2 small ones than 1 big one.
I’ve got another reason why Hannibal’s campaign failed: because siege engines/machines in the ancient world were so bulky and hard to transport, Hannibal simply couldn’t bring them with him over the Alps, even when they were disassembled, so he simply left them behind. This led to one important rule in ancient warfare: you can’t lay cities “to siege” without siege machines.

@@makutamonInteresting 🤔
The first story about the power outage was repeated in 2011 in San Diego, but without the riots, although with an even more stupid cause. An engineer was doing maintenance tests at a major power hub in Arizona and did some steps out of order. The result was the trunk line from AZ being shut off. Which left all the load for San Diego falling on the trunk line from Los Angeles, and that rapid spike caused it to shut down as well. The result was all of San Diego and surrounding areas to be in the dark for 11 hours, with some areas taking up to 36 hours to get restored.
I'm in Oklahoma and Saturday's storms have left us without power. Hinted return time is from tomorrow to the 24th. I know it's not the same, but I appreciate how not having power sucks.

Hey, one can be even more amazed by conviction and triumph vs. stupid oversights that resulted in catastrophe. That last one was brilliant. We need more men and women with that type of gumption, IMHO.
Kudos to the engineer who fixed the building. When watching disaster videos it seems many times the problems are ignored causing the disaster.
Story to tell. Apparently some workers were in the oil mine in the western part of kentucky. I was at home at the time when one of the workers threw down a cigarette and something caught fire. Once it caught fire it caused the whole mine to explode. When it exploded (over 10 miles from our home) we felt the shockwave and our house shook from the blast. I dont remember it exactly but they found their remains. So yea small mistakes, but deadly consequences.
Not small mistake that is what being cheap hiring idiots gets you save a little but then pay out big later
Accidently setting off a fire suppression system at a remote Fuelling facility. Big mess! It was because of me losing my good multimeter. I had to run to a local hardware and buying a cheap one! Big MISTEAK! The releasing panel had a trouble fault on it, so I was using pos meter to test continuity on the circuits and when testing I touched the wrong terminal with the meter leads and heard a pop sound. It was the fire suppression system releasing! I was so pissed off at what I did I smashed that pos meter. I was coursing and screaming so loud that the workers at the facility heard me and were making sure I was ok! Damn! I was so pissed! I had to report back to my company what had happen and the said fix it whatever it takes. Well with in 24 hours we also had it back to normal. $5000.00 later, we also had to pay them another $1000.00 to have a professional cleaning company come in to clean up after we had everything cleaned up. Needless to say, a cheap multimeter and me are to blame. And yes, we lost the account! Got to love it!
MISTEAK??? 😱😱😱
My first job in 79 was at a store as a cashier. There was no digital registers like today. It was a manual register with rows of buttons from 0 to 9 and for the cents, dollars, 10s, and 100s. The 100s were covered as we didn't use them. After cleaning it I removed the cover and the replaced. I rang up the next customer having forgotten to clear it after cleaning. The customer was charged several hundred dollars for that item. The manager fixed the error and I got a warning. Taught me to clear it every time after cleaning.
Oh yes, fireworks can be very dangerous. One New Years Eve, I was outside with my dogs. It had been a very dry winter and I live in south Texas so there wasn't any snow. I watched my neighbors set their driveway on fire. Technically, all the dead, dry leaves but still the whole driveway was in flames that rapidly went above the 6 foot privacy fence. This was right next to their RV which had big fuel tanks. And the neighbor between us is a painting contractor who stores hundreds of gallons of paint and primer in his garage. Fortunately, they managed to put the fire out but I keep an eye on them now as I now know they're not the brightest bulbs.
You're missing a huge part of the City Corp case... The building would've been strong enough if it was built how he designed it but the company building it decided to switch from bolted to welded joints on the metal beams the support the weight of the building. LeMessurier wasn't informed of the change when the building was being built. The student was the one who informed him, after which he re-calculated things and realized it wasn't strong enough
The builder bolted the joints instead of welding them. You got it swapped.
@@hedaron3787Who cares?
@@stellviahohenheimwell it clearly made a difference to the integrity of the building, so...
Mate,You drawing style is out standing!!
Ive been amazed, and learnt quite a bit, this helps me learn when I study.
Fred Fleet's binoculars were not the only "small mistake with huge consequences". The reason the Titanic is so memorable is not because of the number of lives lost or any other reason than the incredibly large number of "small mistakes with huge consequences". For example, it took the ship about two hours to sink giving the people plenty of time to save more people but small mistake after small mistake cost about three fourths of the passengers.
The Titanic had enough lifeboats for UP TO 1178 people. The ship had the legal MINIMUM amount of boats because they figured in the event of an accident, they’d have time to deliver passengers to other ships during rescue. Unfortunately, for the Titanic, the ships that had responded to her distress calls were nowhere near her vicinity at the time. The Carpathia was roughly 54 miles away and though the Olympic, Titanic’s sister, also picked up the distress signal, they were over 300 miles away.
On top of these facts, the Titanic had NO lifeboat drill. One was scheduled the morning of the 14th, however, it ended up being canceled for unknown reasons (though sources claim it was due to Captain Smith wanting to conduct a final service before retiring as he was due to retire at the end of the Titanic’s voyage.)
The cap to the whole thing however, is that most of the boats launched in the “earlier” phases of the sinking were not launched at capacity and this was due to quite a number of factors, but the two biggest being a severe lack of training and urgency, which resulted in passengers believing that there was no imminent danger. In fact, many passengers thought that the launching of boats during the sinking was merely for a drill.
Was just a whole mess!
@@Th3On3Y0uW4nt Don't forget that the Californian was probably less than 20 miles away but miscommunication resulted in the Californian not even responding to the Titanic's distress call.
@@Th3On3Y0uW4nt They would also have had more lifeboats if seeing more lifeboats on the ship was not deemed 'unsightly' as the ship had to look 'nice' instead of practical.
On top of that they had water proof bulkheads in the ship, but only up to E deck as it was again ugly to show such things on the decks that had upper class people.
It was estimated that if the bulkheads were up through the whole ship it would not have sunk with the damage it got.
So too few lifeboats, not putting the water protection through the whole ship, cruising at too high a speed because the captain was sure there was nothing there and it being night which makes ice very hard to see and you have the reason who no-one should say something stupid like 'not even god can sink this ship'. God clearly heard him. and decided to prove a point.
It also has to be taken into account that some passengers were afraid the lifeboats wouldn’t make it and the crew downplayed the severity of their circumstances. They fully believed a nearby ship would get to them before the titanic sank so it made more sense to them to stay put fully believing the ship either wouldn’t sink as it was “unsinkable” or another ship would be there. When most survivors recount their stories they talk about how calm everyone was and that it was so quiet as if they were in church. Just horrible most never had a chance.
Another reason so many people died on the titanic was because the people constructing it didn’t include enough lifeboats for everyone on board
Re the Comet disasters - much of what we know now about weak points, and especially what we know about the repeated pressurisation and depressurisation stresses and strains on the fuselage, comes from these tragedies. Not having computers to help them work out what was going on, they built a huge water tank and put a Comet in it. They put it through many pressure cycles and eventually they found the first "tear". From that they - using extremely powerful microscopes - saw and learned a lot about "creep", where a metal's atoms move in such a way as to weaken it (I know, this is a *very* basic comment, it's supposed to be).
It wasn't just that the windows themselves were wrong, it was that _plus_ the constant pressure cycle. And given that Comet was the first ever jet-engined passenger aeroplane and travelled higher than any other plane, it's not surprising that they didn't think about that being a potential problem.
When we look at the numerous later design problems of plane types that, in most cases, are still around (Boeing 737 Max, anyone?), we _should_ find it impossible to look back at every design fault, particularly with each development in technology (the Max's problem, from what I remember, was from a new tech item or system), and have a holier than thou attitude to it.
I'm *not* accusing this narrator of it in this case, but I have heard, in so many videos, on so many channels, about so many preventable disasters or other problems (if you have 20:20 hindsight...) that I get a bit annoyed. It really does depend on the tone of voice. At least this guy speaks respectfully when there are innocent casualties from any accident or whatever. I appreciate that.
As an aside, it is such a shame about Comet. Once they retrofitted the windows, she had a perfect record, but companies like Boeing were growing more rapidly than De Havilland could, especially given that they were still just recovering from war production and rationing (for the workers). She was a stunningly beautiful plane! For me it's a toss up between her and Concorde as to the most beautiful. I think Comet gets that, but Concorde gets the most awesome prize. Having watched her taking off in Heathrow (on the observation deck - the roof - that was there. No idea if any airports still have them) in the mid-70s, and watching the place come to a standstill - even staff who'd see her daily! - nothing in manned flight is a more awesome thing!
Y did u write so much
There were no cosmonauts on the N1 rocket when it failed and exploded because it was an unmanned test launch. This applies to all 4 of the launch attempts. There were, however, a lot of people killed from the ground support staff.
5:02 Girl, how about blaze
Shout out to our firefighters! They all face amazing dangers.
Amazing dangers that's very opposite
There’s another mistake to the Titanic disaster that wasn’t in this video, but should have been: the tanks/hull divisions that should have prevented the Titanic’s sinking weren’t sealed at the tops, and they were designed so that any number less than or equal to four wouldn’t cause the ship to sink; however, any number greater than four would cause the ship to sink due to “water overflow”, as I call it.
I was expecting them to mention that although steel was used for the central sections of hull of the Titanic, the design called for iron rivets for bow and aft sections. Most of the cracks that opened after its collision with the iceberg were in the iron-riveted forward part of the hull. Apparently the shipyard was overwhelmed by the demands of building three ships at once and therefore directors were forced into compromising on quality, not only using sub-par iron but also hiring extra riveters of less certain talent.
And one more there titanic have secretly have side burn
@@haonsanion8851 Nope, there was not a single coal fire or burn. Even if there was it wouldn't be enough to cause the Iceberg to "damage more"
That's not actually a mistake. That was perfectly normal for ships of the period why watertight doors.
You gotta love William’s story. He didn’t ignore the situation or just tell them off for pointing it out.
He realized his mistake and did everything he could to rectify it.
Do to David Blair’s anger he managed to forget to hand over the key to the safe containing Fred fleet’s binoculars if Blair had handed the key the tragedy wouldn’t have happened in the first place 14:54
It’s debated whether or not the lookout on Titanic would have been able to see the iceberg with the binoculars. Because it was a moonless night and the sea was a flat calm, the iceberg was all but invisible. The only reason he saw it at all was because it appeared as a black mass on the starry horizon. So the binoculars probably would have been useless.
Not to mention the fact that if they were that important the ship would have had multiple sets of binoculars or at least forced open the cabinet they were stored in.
@@emilypower9748I thought that, too.
Fun fact there a TH-camr that does titanic videos called historic travels I think
@@emilypower9748 A lot of safety-related things on the Titanic (most famously, the lifeboats) were skimped or outright overlooked just because no one thought they'd ever be needed. The binoculars were no exception.
There’s a TH-cam channel called “Oceanliner Design”, and the host of that channel is very knowledgeable about ocean liners. He has done many videos about the Titanic, and in one video he explained the real reason Titanic had so few lifeboats.
The reason was that lifeboats were actually more risky than one might expect. In choppy waters, lifeboats were prone to flipping over, and in many situations, were more responsible for loss of life than the ship sinking itself. This was the reason ships were being fitted with things like watertight compartments and all that, in order to turn ships into massive lifeboats in case of an emergency. Lifeboats were meant to simply transport passengers to rescue ships when they arrived on scene. In other words,the new technology made people overconfident, and this was realized in the Titanic disaster. This was why, after Titanic sank, Olympic and Britannic were given the proper number of lifeboats, along with other improvements to their safety features.
Check your facts on the dehavilland story… mentour now did a great video on it… the crashes were caused by metal fatigue because they were able to go really high, meaning that there is high cabin pressure which damaged an opening on top of the of fuselage, not the passenger or pilot windows. There were also other causes.

I was working in a bank, the bank was closed between 12h and 14h each day, in that time we would fill up the ATMs and empty the night safe (where businesses can deposit their revenue after bank hours). I emptied the night safe (which was in an ATM vestibule, open around the clock), I put about 90.000€ in an envelope on top of the safe while locking it back up. I went to lunch and forgot to put the money in our vault. I only realized an hour late, when a colleague asked me if I counted the night safe money yet :D
Regarding the collapse at 25:09: this is the Goffert Stadium in Nijmegen, not Vitesse. More even so, there is no city of Vitesse in The Netherlands. Vitesse is the name of the professional soccer team from Arnhem, just 10 miles to the north of Nijmegen. And even though the stadium was orignally built in 1939, it was completely rebuilt in 1999 (the old stadium was demolished) and reopened in 2000, so all wasn't caused by a lack of maintenance but faulty calculations in construction.
I know of two other small mistakes that caused big consequences. Well, the first one was a mistake while the other was a mishap despite watchful maintenance.
1. The Challenger disaster on January 28, 1986 was caused when a single o-ring came loose, causing the shuttle to break apart upon launching. This disaster was also caused by a lack of a good night’s sleep the day prior.
2. The Columbia disaster on February 1, 2003 was caused when a large piece of foam fell from the shuttle's external tank and breached the spacecraft wing upon launching sixteen days prior. When reentering Earth’s atmosphere, the shuttle disintegrated.

The window shape on the Comet was _not_ the underlying cause of its crash. While it was a weaker point the primary reason for the breaking apart was the manufacturing process that had riveting on a thin skin creating stress fractures later propagating as fatigue fractures through each flight cycle. The Comet would have failed even with rounded windows (albeit probably over a couple more cycles) unless the manufacturing was changed.
You will notice how minimal the rounding of corners are on the very front pilot windshields on modern airliners.
Imo this is one of the best lists on TH-cam to ever exist.
Fun fact: In rocket science, this is known as a 'Rapid Unscheduled Disassembly' or RUD for short.
As an explosion is the rapid disassembling of the weapon.
Your channel should be shown in all high schools, within History and Geography classes. I definitely would of gotten A+ instead of just passing as I found those classes really boring. But I may have become something important given all you have taught me! Thank you! I’m always AMAZED at your content! 💕💕💕
This makes me sad - this is an ENTERTAINMENT channel, NOT educational. You not realizing that means I believe you learned nothing in school and that's sad.
@@ross-carlson I learned plenty in school during the 70’s and 80’s I just found school hard. Yes it’s entertainment but it’s also educational. Sorry that’s just my opinion. And don’t feel sad for me. We can’t all be smart.
@@vujoleenanh Sorry but I disagree as this channel is filled with information and can teach people a variety of things about life.

Apparently you didn't do too well in English either...
The primary reason for the Comets breaking up in midair was the decision to install two oblong windows above First Class so passengers could see the sky.
The square windows were also a factor. They learned what was happening after building a huge tank, filling it with water then submerging a Comet's fuselage in it. Then they pressurised and depressurised it until they discovered the cracks around the windows.
If you want the full story try Wikipedia.
It's amazing how when people admit their mistakes and then work to fix them, people's lives can be saved without them even knowing it.
The reason for the Comet's demise had nothing to do with square windows ... that was an incorrect reporting by the British press. As the Wikipedia article states "Design and construction flaws, including improper riveting and dangerous concentrations of stress around square cut-outs for the ADF (automatic direction finder) antennas were ultimately identified." The real cause was metal fatigue caused by repeated pressurization and depressurization cycles, which was not well understood at the time.
A good video, well done, though I did spot an error in the Titanic section, so here's a quick correction from a Titanic enthusiast:
In 1911, the Titanic's sister ship, the RMS Olympic, collided with the Royal Navy cruiser HMS Hawke, which damaged the ship a bit. The Titanic's construction was put on hold and the Titanic's maiden voyage was bumped back so White Star could make repairs on Olympic. The Titanic's first and chief officers were, before the incident, William Murdoch (demoted to first officer and died when the ship went down) and Charles Lightoller (demoted to second officer and survived the disaster). So the White Star executives had no choice but to transfer Henry Wilde onto the Titanic while repairs on Olympic were carried out, which bumped Murdoch and Lightoller down a rank and kicking Blair, the previous second officer, off the ship, which then lead to Blair taking the keys and the disaster.

Vitesse is the name of a foodballteam (or soccerteam) based in Arnhem. The incident was in the Stadium of N.E.C Nijmegen (wel known for the International 4Days marches) It occuredes at the end of the match between N.E.C. and Vitesse
The Titanic disaster was a combination of blunders. 1st. The captain was on his last cruise before retirement. He wanted to set a speed record which the Titanic was designed to do. When entering the iceberg area he did not slow down to 15 knots, as maritime law required.
2nd. The Titanic was made of riveted brittle
steel that opened like a zipper when she scraped the iceberg. Better steel and welding were developed years later. A welded ship would only have been dented.
3rd. Life boat drills were not conducted. This brought confusion to the passengers. Some lifeboats had 3 or 4 people.
DUMBBELL!! If better steel didn’t EXIST until YEARS LATER….the Titanic’s steel was NOT a BLUNDER!!!!
8:56 as an aviation enthusiast, as soon as I saw the plane right here the first thing I noticed was the square windows which then made me predict of there being a lot of crashes because of the square windows
It was not the square windows that caused the problem.
It was badly made holes for the rivets combined with the skin being too thin and the lack of a way to prevent cracks spreading.
Lazy journalists etc just repeat the same old stuff without checking facts.
@@iscmiscm the square windows caused pressure to build up at the corners making weak spots and the windows could snap and break at those weak points and those holes in the windows was made to equalize the pressure
@@emirates777landatkittila
Sounds great, but the pressure testing after the crashes came to a different conclusion.
Observation tells one what to expect, but testing tells the real truth.
The points of failure in testing were the rivets joining the panels due to the way they were punched combined with the thickness and lack of means to prevent cracks spreading.
Boeing were also able to use the hard earned knowledge on the 707.
Sometimes being first is not the best plus we gave our knowledge for free.
Cleaning lab supplies with acetone, then wiping said acetone with paper towels, then throwing said paper towels into the lab bins. Considering that I was cleaning roughly 2,000 beakers and flasks over the course of 3 hours, that was a LOT of acetone-laced paper inside those bins. Is it any wonder that half the lab was scorched black when, immediately after I finished cleaning, a group of summer camp teens used that lab room to do something related to fire, and they threw their still-smoldering matches into the bin? No one was hurt, though several girls had to walk around with ruined hair and make-up for the rest of the day when the flames causes a downpour from the sprinklers system.
Square windows vs. round windows on a plane.........I learned something valuable today.
Check further.
Clue, it was not the shape of the windows.

It's questionable as to whether binoculars would have been helpful for Frederick Fleet in spotting the iceberg that sank the Titanic.
One thing that people in the crow's nest looked for at night was water breaking against icebergs. The splashing was easily identifiable against a dark background. But with a calm ocean that night, that was not as easy to spot.
Also, with the cold temperature that night, it's possible that the binoculars would have justified fogged up.
@25:14 The stadium in question was from rivaling team NEC (Nijmegen) and the supporters on it are from Vitesse (Arnhem)
"The images show how the supporters jump into the stands and celebrate the three points achieved together with the players, when suddenly the front part of the stands gives way. It appears no one was seriously injured.
It was the first meeting between the two rivals since NEC’s relegation to the first division in 2017. The rivalry between the two teams from Arnhem and Nijmegen is enormous. The match was marred by misbehavior from the stands and regularly running high emotions on the pitch.
Vitesse supporters escaped disaster on Sunday when they celebrated the victory over NEC (0-1). During a party with the players after the first Gelderland derby in 4.5 years, the front part of the branch collapsed." (quoted source unknown)
I was a geriatric medical assitant in Spain, One dayt after an emergency shift of 19 hours the previous day that finished at 1 AM I had to be on a home visit for a checkup at 7 AM but I overslept and was 30 min late, because of this the ambulance that I ordered for that visit had to wait and thye had to call another one for the other patients and that of course lead to the delay of 9 ambulances and a mixum pf 2 hospitals for patients. No fatal injuries but just a huge delay in the checkups of a city that day because of me in 2018
Thank God William was open minded enough and didn’t have an ego problem, so that he listened to Diane about the structural flaw of his NY building. In a different scenario, he could have ignored her and disaster may have followed. Good on both of them. 👍

I made a mistake at work once. I was upset about it but my boss said, "If you do not make mistakes you are not doing anything worthwhile."
I had a date that night and we went to PF Chang's.
It was good food and delightful conversation. While we ate I told my GF about the mistake and what my boss had said. We laughed about it, with her commenting that with her job, mistakes tended to be a bit more catastrophic. She was a cardiac nurse.
We got our fortune cookies and I cracked mine open, read it, said, "I don't believe this!"
I showed her my fortune cookie and we both laughed.
I even took the fortune to show my boss the following Monday. The fortune read, "If you do not make mistakes you are not doing anything worthwhile."
He smiled and said, "Where do you think I got that?"

The comet windows aren't square because the corner of it is smooth, it's not sharp. The crashes was caused of fatigue on the structure
(please add anything that I have missed)
Yeah, Mentour Pilot has a vid or two about this. Blaming it on square windows was just poor reporting that has been passed along as fact for years and years now
@@MrGoesBoom Yep
Yes, fatigue added to the corners.
10:38 That wasn't the source of the pressure. The source was internal - the plane was flying in extremely thin, unbreathable air at around 40,000 feet but was pressurized internally to the equivalent of a breathable 8,000 feet. This substantial pressure difference, combined with the cyclic nature of its application due to landing between flights, caused the metal around the window corners to fatigue.

You did point out a good flaw when it comes to the sinking of the Titanic and many lives have been lost, but there were others. Flaw 1: number of life boats. If the trade regulations were not out of date, then they were able to do 64 life boats instead of 16 which means many lives would have been saved. Flaw 2: coal fire. There was a coal fire in one of the coal bunkers that weakened the hull. They decided to put the fire out and continue on with their voyage instead of going back to Holland and Wolf for repairs. Flaw 3: ignoring ice warnings from other ships. The people in the telegraph room were so occupied with messages from passengers to Cape Race to family and friends that only 1 or 2 ice warnings went to the captian, not all of them.
Thanks for pointing this out because not much people know about how the titanic actually sank. Basically the coal workers were trying to get the coal out as fast as they can to put the fire out but this made the ship stay at high speeds through the iceberg zone and they just kept putting more coal into the engine so the ship never slowed down too avoid the iceberg
Wasn't there also a fire before it's launch as well
@@vexile1239 theres also the theory the titanic was secretly replaced with her sister ship before the voyage. the two being nearly identical. I don't remember all the details of the theory but it seemed very viable
Nope, there was not a single coal fire or burn. Even if there was it wouldn't be enough to cause the Iceberg to "damage more"
Actually, it was a series of errors that lead to the sinking of the Titanic, not any single one! A coal bunker fire leaving the bulkheads compromised and the ship listing (with visible signs on the hull if you look, you can clearly see where the metal had darkened from said fire STILL BURNING when the ship first set sail) and not to mention the order to pull full reverse and to turn hard, plus the First Class passengers leaving all their windows open - I am not making this up; these are genuine factors that contributed to why she sunk so damned fast!
Nope, there was not a single coal fire or burn. Even if there was it wouldn't be enough to cause the Iceberg to "damage more"
@@reddwarf5133 There was a coal fire, the bulkheads were warped from it! It was raging well into her maiden voyage! She was well out into the Atlantic before they got it under control! You can clearly see a dark spot on her hull in the photos of her, bearing in mind she was listing as well! And I didn't say it caused more damage, it compromised the inner hull integrity, which did not help!
nah the thumbnail is wild 💀
The titanic disaster was also the captains fault.
Since he turned the ship was damaged more then if he went head on to the iceberg
WRONG!!! Going HEAD ON would NOT have sunk the ship. The boat DRAGGED along its SIDE, ripping open SEVERAL compartments!!!
The Comet did not crash because of it's windows. This is a common misunderstanding of the comet crashes so don't worry.
The planes actually crashed because of tiny fatigue cracks which were created when the plane's bolts were made.
The speed of the De Havilland Comet had nothing to do with the crashes. The issue is the pressurization and depressurization cycles causing metal fatigue.

I'm from Minneapolis and grew up going to the Metrodome. It wasn't an oversight as much as it was just an old building in need of renovations and an unusually large snowfall that year. The building was already being planned to be either demolished for a new stadium to be built or have a huge overhaul. Not a mistake - just neglect 😊
Same here. Every game I went to at the Metrodome I kept looking at the ceiling thinking that at some point it would break down. It did when I was in my 20’s. The Metrodome was still active for small events like the Rollerdome. No games were held till Target Field was built and a new Vikings stadium was built after the dome was demolished. Good memories before that disaster happened.
Gotta leave the heat ON in the winter!!!
The deHavilland Comet despite its flawed square windows was nonetheless one of the most beautiful aircraft ever built.

Slight correction about Carthage. The famous phrase "Carthago Delenda Est " or the full phrase "Ceterum (autem) censeo Carthaginem esse delendam " was said after the 2nd Punic War and was said by the politician Cato the Elder trying to convince the Roman senate to intiate the 3rd Punic war, which he was eventually able to do.
