I am very appreciative of the support that Juan has given me sit I started my page three years ago. My channel is a pale comparison of what he does weekly when it comes to aviation. You have set the bar high sir! Thanks. Your buddy Sal!
I can see this Bridge clear as day from the back of my job. I’ve seen this bridge my entire life. Rode across it last WEEK. It is mind boggling to see it not standing today.
Sal's updates have the early facts, well communicated. There's an NTSB press conference shortly (maybe 15 minutes, but it keeps getting pushed back) that will be live streamed on their TH-cam channel.
I live in Maryland, and this is crazy. My cousin works for the state of Maryland and was working on the key bridge as a inspector. We had a very tense morning but luckily he was not working that shift but knows the guys who were. I don't think people realize how high that bridge was off the water it's just unbelievable seeing what happened
You're such a Class Act Juan. Not only making a video while away but such a sincere and unabashed plug for our pal Dr. Sal Macoglian of 'What's Going On In Shipping". You two are so alike in many ways.
I heard the bridge crash at 1:40am, sounded like rolling thunder and a small earthquake, house windows rattled slighty. I live about 12 miles as the crow flys from the bridge. I did not know at the time that is what was until I got the morning news. So sad for Baltimore and Maryland as this will affect so much in the metro area.
Thanks for the diversity of your reporting, not just aviation (although that's my connection); not just Oroville and the other dams or Tulare Lake; California snowfall etc, but a diverse subject matter that affects us all, in a concise, polite and factual manner.
The FSK Bridge support columns do not appear to have "Dolphins and fenders" commonly seen on many bridges (ie. Golden Gate, San Francisco, etc.) which lessen or deflect the impact of ship traffic. The Dali struck the concrete support which destroyed it, and the cascade failure of the entire arch beam structure. Bridge columns have been protected by fender systems for decades. This bridge (b.1976) should have had those as part of the original design. Incredible how fast the collapse occurred. The power transmission towers just next to the bridge do have "fenders" affording better protection than the bridge had.
The new Sunshine Skyway bridge in Tampa Bay, which opened in 1987 has two different methods of protecting the towers, after a similar collapse in 1980.
After the Tampa bridge was destroyed in a similar collision in 1980, federal regulations changed the requirements for size and mass of caissons to protect against future ship damage to bridge structures. The Keyes bridge in Baltimore was built in 1977. No provisions were instituted to upgrade bridge protections and support structures for spans built prior to 1987.
The radio here said that the captain called in a Mayday and the bridge was quickly shut down to traffic... which 100 percent saved lives. At least they had that going for them. Prayers for all involved and hoping for the best. This one could have easily been far worse.
They sure did. In the early parts of the live stream video there is a lot of traffic on the bridge, but then you notice flashing lights and a decrease of traffic crossing not long before the ship hits. Unfortunately those flashing lights are on the traffic control cars that end up going down with the bridge. They saved a lot of lives with their quick response but may have paid with their own.
I’ve crossed over and under that bridge many times. I suspect the cargo will now move through the C&D Canal and into the Delaware Bay and up to Trenton and Philly. Crossing that bridge had an excellent view of Ft. McHenry from 100’ up. Gov. Moore will build back better. Plasma cutters wanted. Underwater Certification required. Excellent pay and benefits.
Hi Juan, thank you for the video, appreciated. I am already subscribed to Sal’s channel, it’s excellent. What he’s said so far is more detailed and makes more sense than the mainstream media’s talking heads.
What's going on with shipping, done watched two of the videos a couple of hours what's going on with shipping, done watched two of the videos... Good stuff.
The fire department has the saying “you never trust the trusts” because if there’s any impact to any one point in the structural integrity, the entire trust system fails
It may not have anything useful on it. It may have not had any backup power supply. Even the blackboxes on airliners shutdown with a total electrical failure
WHY don't the tugs stay with the ships until the freaking bridge is cleared? According to Sal Mercogliano ("What's Going on With Shipping"), they depart once the ship is escorted to the shipping lanes. Considering the risk, it seems like a small operational change that could have saved human lives, BILLIONS in repairs and losses due to the port closure and highway detours which will probably last 3 years. NONE of the news outlets are looking at this!
I usually went on this bridge when I drove to eastern Pennsylvania. I took this route in late September and construction crews were working on the road deck at the time. Having looked at the aerial views of the bridge (pre-accident) there doesn’t seem to be a great deal of bridge pier protection above the waterline. I don’t know if there are any protective structures below the water. Update The NTSB has released some aerial or drone video that is astonishing. The superstructure or piers just basically crumbled.
Enjoy the rest of your holiday mate ,safe travels,hopefully no fatalities though we did have a similiar accident in Tasmania a few years back,thanks again,👋👋🙏🙏👍👍🇦🇺.In 1975 a ship struck a pylon of the Tasman Bridge in Hobart,Tasmania collapsing the centre structure,there were several fatalities.
generally speaking, "Never go faster than you are willing to hit something at when in harbor/port" because things can always go bad fast. I know structures are made to take some impacts, yet I am curious how much have ships gotten bigger over the years vs when the bridge was made, and did the port authority consider that when saying how fast ships can go in the channel?
Sals video is great and sadly seems to be overlooked by the nonsensical media. Thoughtful analysis, with data tells one important piece of the very sad story. More to come and prayers for all affected by this tragic event. Thank you for sharing and safe travels.
It's a terrible accident with loss of life, but it's so fortunate that didn't happen during peak hour when presumably the bridge would have been full of vehicles.
Sounds like a main breaker/disconnect with a time delay to reconnect. If you've ever had the power go out in your home, and it tries to reconnect, it's similar. Usually there will be three attempts to reconnect, idea being the fault may be cleared. Like a tree branch brushing against a power line. Not a hard fault, but something perhaps worn cable, loose electrical connection etc. Marine environments are incredibly corrosive. Lots of vibration too. Providing they can stabilize the ship and keep it from sinking, they should be able to go over the ship's electrical system in great detail. We'll have to wait & see, but that's my 2¢ Terrible thing for everyone affected.
Ship seemed to be on a good course even when the lights went out. It seemed to be only when the engines kicked back in (Big cloud of black smoke from the funnels?) The the ship kicked hard right straight into the path of the pillar?
Depending on which direction the single massive propellor turns, it may have contributed to the ships direction of travel when going astern. They call it paddle-wheel effect when the prop cants the ships head like that. Not a problem with twin screw vessels as they counter each other.
Holy sh*tballs, this has been breaking news here in Australia, too. In some of the far shots of the bridge, you can see amberflashing lights, onestationary, one moving, and as the shot tightens, you can clearly see the moving one is a car. I hope like heck they find those people in the harbour. As of right now, I understand there are still 6 missing.
FDC 4/1803 No pilots may operate an aircraft in the areas covered by this NOTAM. Radius: 5 nautical miles from the surface up to and including 2000 feet MSL. Ending Date and time: Permanent "No deficiencies were found when the vessel was last inspected on September 9, 2023 by the US Coast Guard in New York."
My take as a retired mariner. The ship lost main engine power which renders the rudder ineffective without any prop wash over it (no steering), or the ship lost electrical power with the rudder stuck to starboard until power could be restored to the rudder steering gear and counter rudder applied. Many ports that have bridge structures close to a navigable channel, build small islands around the supports as a buffer for grounding and prevent the structure from being impacted. Also, some ports make escort tugs mandatory for very large vessels to prevent groundings or collisions. I know, that's expensive but that's the price of mitigating a disaster (which this is, and it could have been a lot worse if it were during the daytime). Well Done (BZ) to the ships pilots on calling the mayday and the MD bridge authority responding by closing the bridge to traffic. Sad those workers died though...
With 20/20 hindsight the support is very fragile, there should be substantial pilings 20 meters out or more with layers in the direction of travel. I think foreign vessels coming into the port from the ocean need a local pilot, I will assume that and if there is blame that is the guy to blame. They should have had a tug stationed at that bridge in communication with that pilot for such an emergency, it hangs around and shadows large ships passing under the bridge. The safety of these waterways is in the hands of the probably state and local politicians, big money, lobbing, budgets put safety on the cheap with a less is more slogan.
I saw in another video, a veteran merchant marine captain said that it was common practice to test an emergency reverse process before entering the harbor, and that maybe that had caused a failure. He also said that the bow thruster has little effect above 5kts. Maybe that caused some engine failure and then there was little that could be done. It does make me wonder if bridges like that should be designed so that each span could remain intact on its own. That catastrophic failure was pretty crazy to watch and was inevitable, given the way the spans were attached to the piers.
I feel the Port authority failed to mitigate such an accident as bridge obviously did not have sufficient collision protection, that is negligence. For the ship to lose power and go black means all generating sets were off the board, as a minimum of two set would be running, a third on warm standby the failure was likely on the 6.3 kV. Cpt's knew he was stuffed making that Mayday saved lives.
when i was a kid a ship ran into the Rio Vista bridge across the Sacramento river & got lodged there. I remember my parents taking us to look at it, maybe a one minute or less drive from our house. The bridge is built very well & didnt collapse, only broke one section. Thick fog was a factor.
Enjoy your vacation - when you’re back can you cover the near miss at LGA where a plane nearly hit the tower before going around and eventually diverting to Baltimore? Would love more perspective on what could have possibly happened for the pilots to end up so far of course
Steering is usually hydraulic on these large ships. The hydraulic actuators get their fluid from large electric motor powered pumps. Two pumps may be running with a third as a spare. There seems to have been only one electric generator running as everything went down together. Generator problems or maybe the switchboard.
I noticed that about 900 people were watching an aircraft at Baltimore on Flightradar24. When I clicked on it, it turned out to be their police helicopter. And it was going wild. It was doing circles around places all over the city to the north of the bridge. The track looked like a bowl of spaghettis. Something was up. It seemed to me like they were looking for something with all the many small circles they were making in different places.. I should have captured it.
@@mderline4412 LOL! I actually grew up in the western MD mountains. Had an Aunt who was a parachute rigger at the Martin Co. during WWII, so we'd drive down and chase crabs around her yard on Cape St. Claire.
I'm surprised at how easily the bridge collapsed. I lived in the California Bay Area in Antioch and West Pittsburgh, now Bay Point, and the bridges there have a significant abutment; I'm wondering why the ship didn't put out the anchor.
Juan, can you discuss the incident that VASAviation reported on about the tower near miss on approach to ILS 4 at LaGuardia? Only after you get settled in from vacation, of course 😊
Um, "Sir" Francis Scott Key" bridge? I don't believe Francis Scott Key was ever knighted. Thanks for the heads up about Sal's site. Very interesting and informative.
Very tragic accident, Swedish newspapers report on it, including the newspaper "Aftonbladet". They had a very intelligent comment "The road is closed in both directions"
But nobody seems to answer why ship backup power generators weren't running beforehand as normal as well as alternate rudder pumps. Sal's comment section too inundated to get answers.
Why didn't the ship drop it anchors if it was not controllable, and having issues as an emergency way to slow or stop? Thought that was ship stuff 101?

Between you for aviation and Sal for shipping, there are no other TH-cam channels the cover detailed, knowledgeable explanations of current events!
Lets not leave out 'Ward Carol' .....another great channel.
Yeah, let's not leave out Ward. He has a hell of a channel.
LOL. I ran across his channel this morning and said to my wife: "This guy seems like the 'Juan Browne' of shipping."
The SOS put out before the ship hit the bridge prevented more drivers from crossing the bridge.
In this case it was a Mayday call, probably by the port pilots that were embarked.
I appreciate the link to Sal’s page, Juan 👍 thank you!
Sincere condolences from the UK for those lost and affected in this shocking event.

Sal said there were modest fenders.
Nothing is going to absorb the impact from a 100,000 ton container ship.
How "quickly it collapses" is solely determined by the acceleration of gravity, 9.8 m/s^2 (or whatever it is in your units).
After the Tampa bridge was destroyed in a similar collision in 1980, federal regulations changed the requirements for size and mass of caissons to protect against future ship damage to bridge structures. The Keyes bridge in Baltimore was built in 1977. No provisions were instituted to upgrade bridge protections and support structures for spans built prior to 1987.

Well, that’s just the effect of gravity and stress propagation throughout the adjacent sections. It’s a suspended bridge…

@@Plisken65 no problem, Worzel.
I was thinking earlier today, I bet Blanco is going to do a report on the bridge.......
Ships don't have multiple redundancies like aircraft.
Ships going out of control in harbours and causing huge damage is a regular thing.
Unfortunately that is true. so many videos on youtube of ships out of control.
Thanks Juan for giving us good sources of information.
Thanks Juan for the update and the link to Sal's channel.
Thank u Juan
Horrific! That bridge came down like toothpicks, hard to believe it is made of metal. So sorry for all those involved in this tragedy.
Seeing this this morning as a Blancolirio video I immediately thought “that had to be one LOW FLYING plane!”
Do ships have black boxes like planes?🤔 Is there a bridge voice recorder and instrument recording?
Yes that ship will have a black box.
It may not have anything useful on it. It may have not had any backup power supply. Even the blackboxes on airliners shutdown with a total electrical failure

Hi Juan, will you a video on the Qantas A330 that did a copy book successful single engine approach and landing into Perth a couple of days ago.
My take as a retired mariner. The ship lost main engine power which renders the rudder ineffective without any prop wash over it (no steering), or the ship lost electrical power with the rudder stuck to starboard until power could be restored to the rudder steering gear and counter rudder applied.
Many ports that have bridge structures close to a navigable channel, build small islands around the supports as a buffer for grounding and prevent the structure from being impacted. Also, some ports make escort tugs mandatory for very large vessels to prevent groundings or collisions. I know, that's expensive but that's the price of mitigating a disaster (which this is, and it could have been a lot worse if it were during the daytime).
Well Done (BZ) to the ships pilots on calling the mayday and the MD bridge authority responding by closing the bridge to traffic.
Sad those workers died though...
With 20/20 hindsight the support is very fragile, there should be substantial pilings 20 meters out or more with layers in the direction of travel. I think foreign vessels coming into the port from the ocean need a local pilot, I will assume that and if there is blame that is the guy to blame. They should have had a tug stationed at that bridge in communication with that pilot for such an emergency, it hangs around and shadows large ships passing under the bridge. The safety of these waterways is in the hands of the probably state and local politicians, big money, lobbing, budgets put safety on the cheap with a less is more slogan.

This bridge will take years to rebuild.
When the sunshine skyway bridge here in Tampa bay collapsed in 1980, it took seven years to rebuild that similar type bridge.
Thanks Juan and thanks for not calling the ship a boat 😂
Good stuff as usual. Looking forward to a more detailed analysis of this preventable incident. Thanks sir!

I watched his video earlier today, before the networks got it.
From what sal said in his video, i think the ship lost rudder control mid turn, and thats why they tried an emergency stop.

Interesting comparison! Worth reading the Wikipedia article.

Um, "Sir" Francis Scott Key" bridge? I don't believe Francis Scott Key was ever knighted. Thanks for the heads up about Sal's site. Very interesting and informative.
Why aren't tugs required? I thought they were within harbors, but not?
The entire section of bridge collapsed in mere seconds. Terrifying and fascinating in equal measure.
Are you as surprised as me on how fast it all came down?
It's a suspension bridge... They will fail completely if something happens to a support column.
Like losing the top of an arch, it will just crumble.
How "quickly it comes down" is solely determined by the acceleration of gravity, 9.8 m/s^2 (or whatever it is in your units).
Reminds me of the old saying: “Any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands.”
I wonder if anyone shut off the wheelhouse audio and data recorder on the ship after the impact!
Lots of questions, hopefully thorough inquiry
Very tragic accident, Swedish newspapers report on it, including the newspaper "Aftonbladet". They had a very intelligent comment "The road is closed in both directions"
But nobody seems to answer why ship backup power generators weren't running beforehand as normal as well as alternate rudder pumps. Sal's comment section too inundated to get answers.
Why didn't the ship drop it anchors if it was not controllable, and having issues as an emergency way to slow or stop? Thought that was ship stuff 101?
It did drop port side one. It likely didn't have enough time to become effective.
