- Why aren’t commercial flights getting faster? Dig into the technological and environmental problems facing supersonic flight.
--
In 1996, a British Airways plane flew from New York to London in a record-breaking two hours and fifty-three minutes. Today, however, passengers flying the same route can expect to spend no less than six hours in the air - twice as long. So why, in a world where everything seems to be getting faster, have commercial flights lagged behind? Alex Gendler details the problems facing supersonic flight.

The two sets of wings to create two waves to cancel each other is a genius idea.
It looks like a star destroyer
But that makes for more materials meaning more weight meaning more fuel :/
@@rollon1181 Yes, I agree with that but the problem with a supersonic plane is the speed because Energy is proportional to the velocity squared. So, I think they are not aiming for reducing fuel consumption with the idea, but they are reducing the noise problem. The idea of using overlapping waves is smart because it should be intuitive, yet it is not. (for engineers at least).
@@rollon1181 Not necessarily, you won't need as big wings if you have 4 of then rather than 2.
@@Eric-zz5ij No, the lift created by each pair of wings will be relatively similar to one slightly larger wing, so it will actually require a lot more mass. The other problem is that whatever connects the two will need to be able to absorb much of a sonic boom every time it flies. So even more weight meaning more fuel.
Instead of trying to reduce fly time, reducing the time spent on boarding plane is more practical
Plane boarding is actually very efficient. It's just the lines that make everything longer.
Time spent boarding planes is actually just waiting for the flight because parents leave at 5 am for a flight at 2 pm
Interestingly enough the current boarding process could be much faster and is actually potentially slower then just boarding the plane in a random order. However no airline uses the most efficient boarding method simply because people will never all listen and form a line in correct order (someone will board out of order massively slowing the process down). It would also mean that first class would board at the same time as business class defeating the point of the higher price ticket.
@Sharkie explain?
you say this until something unexpected happens and you have arrive at the airport 15 minutes before boarding ends
I remember someone saying once that the majority of people who flew on Concorde would have had no idea how much their tickets would have cost, because they were wealthy enough to have personal assistants to book their flights and accountants to worry about the price...
That’s quite true… Concorde was losing a horrendous amount of money in the seventies and early eighties. I think there was no Concorde premium… tickets cost the same as First Class.
So BA (and presumably Air France) polled her passengers as to how much their tickets cost. Most of them had no idea and guessed at a price that was far more than the actual cost of a ticket.
So prices went up to match expectations and she became profitable.

Oooh that "catch me if you can" inspired animation. I love it
I think I missed it, at what time was it?
@@alexandermaxx same
Idk i think the whole vid?
Exactly my thought!! Loved it
omg you are right! no wonder it kinda feels familiar. love it!
My mother worked on the concorde during 8 years if I remember well. She met so many celebrities and I love hearibg her tell me those stories :)
How many mother's worked on Concorde? I have seen dozens of people say their mothers worked on it.
@@genocosta7240 "Worked on" is pretty vague and considering a project like that probably involved at least a thousand probably multiple thousands of people in one way or another it's really not that surprising. Remember this was before CAD existed and entire drafting rooms full of people were needed to do what today could be done by a handful of engineers.
@@genocosta7240 also pretty sure OP meant their mother was a flight attendant. Idk why the engineers would be meeting celebrities at random
When I was a kid, my school was near an airport. Whenever a plane took off it rattled the windows of the classroom and all we could hear was the roar of the engine. That all stopped right when the Concord went out of service. Now I finally know why this stopped happening! Thanks Ted-Ed! 😁
Well, that wasn't a sonic boom, that was the afterburners. But yeah, they're loud, too.
perfect animation
gave me catch me if you can vibes
Just like always 💯
Yup
They've had great animations before but this really takes top prize, its so smooth
@@IlValentino100 The music from the opening credits to that movie was playing in my head when I watched this

This is so engaging. Not at all monotonous instead fast moving and connected with varied facts and information. Super!!
As Always Ted Ed has Raised the level of education with animation!
It's way easier to learn this way.
You know non of my history teaches know this when i told them.
I guess im not the only one
Clearly you haven't discovered Kurgesagt yet
@@sanjaimj I've watch them they're really good at animations. But the thing with Ted ed is that they use new art style every other video. Kurgesagt hsve their art style which they consistently use.
@@sanjaimj i have but somehow i love Ted Ed more!
I feel like my IQ increases by 1 point every time they upload a new Ted-Ed video.
More than that
I guess if you are starting at 0, you would see this slight increase.....
SAME!
Me too. Now it's 75. ;)
More like decrease 👍😎
I request TED-Ed make animations like this for next videos.
This kind of animation is so wonderful and aesthetic. One of the best animation so far!!
This video's animation is a cut above the others. So satisfying to watch
The drag coefficient increases dramatically as you approach the speed of sound, then trails off as it passes Mach 1, but supersonic flight isn't viable for commercial flights because of a) sonic booms rattling homes and b) fuel costs needed to power the engines. So what airlines do is keep the speed at about Mach 0.85-0.9, just before the exponential drag increase kicks in.
interesting
Thank you for your efforts, TED-Ed.
This is one of those videos you just feel thankful for watching. Great job and brilliant summary 👏🏻
I thought I knew the basic of why, but this explanation is clear and understandable. There is so much new things I learned.
Ted ed, you are honestly the most simplified educational channel ever! I even follow you on Spotify. Hope these videos continue to change the world
The animation is just hypnotizing.
REALLY good to see!! This animation is perrrrrrfect!
Great topic and the animation is simply perfect.
TED-Ed answers all that questions that we don't even think ❤️
Key word in your statement is "think".....seriously though!
Yes
GirlBabes.men
you mean questions 'you' don't even think
The animation really fits the topic. 👌
really cool vid! wasn't expecting to learn this today but love it
Love Ted Ed. Animation was amazing. Really interesting subject, well summarized
The all aesthetic animate is just dope
Man these animation and sound effects are damn good
Another problem with Concorde was they had to have certain requirements for runways as well as taking of and landing could not be done with aircrafts in a certain radius of the airport. It wasn't just the cost of the aircraft itself but also the runways and other complications it caused with other aircrafts making Concorde unsuitable for airports unless requirements were met.
I grew up on the funny story of my dad learning to fly a light aircraft and that a Concorde aircraft was made to wait until he landed.
I’d heard was one of the reasons that Concorde wasn’t given more US airports was simple jealousy. The US airline industry had nothing comparable and the C rubbed their noses in it. So they amplified the complaints about it to stymie the project long term.
This video was far more interesting than I'd anticipated.
Love it
people commenting are faster than the planes mentioned
I dont get airplane jokes
They go right over my head
lmao
This is why I quit being an engine mechanic. It’s exhausting.
And into 2 buildings
It's you again! Didn't you just heart my comment? Small world...
@@macaroon_nuggets8008 it really is hahaha
Love the new animation approach! Great video, too.
One key element neatly left out is that aircraft can go to higher altitueds where air resistant is sufficiently low, yet dense enough to provide oxigen to the engines while significantly reducing air drag. This has been known for decades, but the resulting economies would be of such a scale that airlines would not be able to justify the already inflated prices.
Safety issues.
yeah but then you become severely mach-limited. Speed of sound decreases with altitude, so if you go to high, you won't be able to stay in the air at Vmo
There are 4 forces that act on a plane: thrust, drag, lift, and weight. Planes slow down because of drag. Once power is reduced, drag is greater than thrust and causes the plane to slow down.👍
and drag components become funny after you reach supersonic flight...
man I love ted ed's comment section
you forgot one more resistant force: the FAA pilot certification
i smell aerospace engineering
its a very strong smell LOLOL
(I live in a city full of aerospace nerds)
What you are describing is parasitic drag, but the other factor is induced drag which increases as an aircraft slows down. Get too slow, and induced drag becomes so great that it takes massive amounts of power to keep the aircraft in the air even at very slow speeds.

I perfectly understand people's frustration with sonic booms and why planes were regulated to stop causing them. I grew up with my grandparents. They owned a farm near an airport. Farm was very close to it so you could see every plane landing and taking off.
Quite commonly military jets were taking off from there as well for some reason. And Jesus Christ.... you could see the shockwave when they take off. The sound is extremely loud, all windows vibrate like crazy. Volume is like 1AM in a club.
We didn't live on that farm, only were coming in to do farming. But if I'd live and sleep there I'd go crazy.
I grew up a few miles from the airport. There were entire communities moved because of the noise of the airport, and damaging homes. This was not even supersonic stuff. They moved neighborhoods, and changed flight paths, for general aviation, alone. They built a newer bigger runway for the new bigger planes, and tore down another few communities to achieve that. I'm going to leave out military planes, from this topic, because those are another level of loud. I hear the afterburners quite often.
Growing up, I heard about lawsuits and legal problems from planes damaging homes. Over time, It seems they would rather buy out communities than to pay on lawsuits. Thankfully, they changed the routes above me, also.
Strangely, another factor is that the city owns the airport, in the county land. You can only imagine what kind of dynamics that creates,. ( county neighborhoods suing city airport )
I grew up not from from cars, trains and planes, all times of the day, and they just become normal. At some point, you just don't really hear them anymore because your brain just blocks it out. There are times when you have to stop a conversation waiting on an airplane to pass. It just becomes background noise, and it is very rare to lose sleep over it.
There is a golf course, near the airport. One of the attractive features is that you can hear, see, and feel a huge wave of swirling wake turbulence coming down the fairways. It is horrifying if you dont know what it actually is. The golf ball swirls, the trees shake, the noise is like demons coming from who knows where. Good times.. I actually recommend it.
Fascinating video!
Thanks for explaining.
I really love the art style, it just screams "jet age" 🤗🤗
3:23 there is an error, the sweap does reduce the wingspan, but it really reduces the lift. Planes are normally designed (by my understanding) with a set wingspan (bc of airport restrictions mostly). Then the angle is given. Planes with a high angle are for high speed, subsequently lower angle wings are for lower speed and higher lift. That’s why most piston engines and small planes have either no swept wings or very low angle swept wings. Great video though.
this is a very educational and fascinating video... I love it!
The animation is amazing. Good job 👍
Now I want to watch Catch Me if you Can.
imagine being in the cabin of the Concorde going faster than sound. Especially if your the pilot...
And later on landing and finding out that your twin brother got much older than yourself. No thank you
@@amarilloatacama4997 Relativity in a nutshell
It was amazing.
I had a misconception as a kid that if you were in front of the engines, you wouldn’t be able to hear them until you went below the sound barrier. Of course that isn’t true, the speed of sound is relative to the emitter, so you would hear the engines just as well as if you were stationary.
@@benisjammin8926 what a cool yet random fact
Excellent presentation
Thank you for increasing my knowledge..
The video should also mention that an Airforce major harnessed the power of the sonic boom into a projectile weapon. His name is Guile
Hahaha you can see now how difficult and deadly this technique was ...

@yabghus, what kind of whacked out troll job was that?
In 2000 as an airline employee I rode Concorde for an inter line rate of $500 ! Best money I ever spent ! Came back on a DC-10 - seemed to take forever !
Far too often when we all talk about scientific progress we make bold claims of technologies we'll have in 20-50 years...this progress is only achieved through millions of men and women dedicating their life labor to their science, and sometimes the progress is slow or non existent. Still waiting on those fusion reactors everyone said were right around the corner in 1995, I guess we'll just have to settle with micro improvements to cell phone cameras moving forward.
With fusion reactors we've actaully already achieved the ability to have nuclear fusion power. The problem actually is practicality since when we do it we end up in a net negative. So the challenge is creating a large enough net positive to outweigh it. The day we figure it out and can apply this on a large scale would change human history. Which ITER is trying to do.
@@levelfourteen I worked in the fusion nuclear research field for some years, and I can tell you no we don't have the means to utilise fusion power, nor anywhere even near it. ITER is an experimental test reactor, not a power station. We won't have fusion power in 20 years, and possibly not in 200 years. Fusion of deuterium and tritium at 110 million C in a brief burst, is not the same as yielding fusion power. Even if the power extracted can exceed the power needed to run the reactor, that's nothing compared to the other advances necessary to make fusion power viable.
it only takes one person
That's what happens when you take the media dramatisation seriously. Everything gets highly exaggerated because otherwise people aren't interested.
The people making bold claims are the media, not the actual scientists
I will always find engineering fascinating, how they come up with these solutions amazes me
im always excited when i see a video like this and know the answer
I wish I could fly the Concorde one day, it looks so elegant and majestic.
United is bringing them back 😎 your day is coming my friend
Was this animation inspired by the Catch Me If You Can opening credits? It seems like it, and it'd fit the topic at hand as well.
This was fascinating!
This is a very well done mini documentary
I'm pretty sure there were additional reasons for retiring concord!
That accident on takeoff from Paris may have played a part, and gave them a good time and excuse to retire it. I suspect it was always economically marginal.
The video by Mustard goes even deeper into the Concorde's development.
The concord was never a profit driven product. It was a national prestige and political endeavor. If a product is not market driven it will be an impractical, unwanted item
"Hybrid electric planes" Good luck maintaining twice as much as now. Maintenance costs, speeds and reliability is something to consider as well.
Very interesting and informative. Thank you.
Excellent explanation
Wendover Productions: Stay out of my turf, Ted. 😆

This is quite possibly the dumbest comment on TH-cam. And that’s saying something.
@@Milesco Well, that is true
I think the answer you’re looking for is ‘they have mass’. Speed of light is a concept and a... -relatively- interesting one at that!
This was something I was thinking about recently. I already knew a little about the sound waves of a super sonic flight being too much, but this made me understand the whole situation very easily. The animation was beautiful as always ❤️

Your videos are awesome.
4:20 How exactly does that double wing produce lift? Does it require a positive angle of attack? Also, I love plane videos
420 🥦🔥💨
Can we just appreciate the brilliance of Concorde. Designed and engineered without computers on drawing bords in the 70s, when anything still was thought possible.
I hope we achieve a viable supersonic flight concept in the not so distant future even if it's still very expensive since there is not getting around the F_d ~ v^2 (drag force proportional to the velocity squared) not matter how much you change c_D (drag coeff.) and A (reference area)...
🤩 great video love it 😍!!
Best Ted talk Ever 🙂!!
long story short, fuel and sound go *brrrrrrr*
We haven’t been to the moon since the 1970s ! If someone asked me how far in space man has traveled and what we have done, I would have been sure we would have colonies on the moon and Mars by now. If someone told me back in the 70s in 2021, we had not been to the moon in over 40 years, I would have assumed there was a nuclear war that destroyed most of civilization.
oh no . they (we) went to the moon - its just the 380 odd thousand kilometers in between that was the awkward bit
I agree 💯. We have pretty much regressed since the 60s. Extremely
disappointing.
My toaster is more high tech than what they apparently flew to the moon.. all the tech we currently have and we can’t get past the van Allen belts, nasa admit they can’t get past them… yet we did it in a tin foil space ship 60 years ago…….. 😂 yeah sure.
Great video
This animation makes the complex summary seem like a children playbook. Very easy to comprehend.
I would imagine the idea of an advance civilization isn’t about all about having a higher IQ but the ability to simplify complex information enough, that a huge number of individuals can learn so much in little less time without frying their brains.
Imagine going on a flight and midway through it the plane just says: *LOW BATTERY. PLEASE CHARGE*
Probably why they are already training passengers to carry their power banks in hand baggage - so pilots can plug the plane into them in an emergency.
Simple answer: they're trying to save on fuel costs by going slower. Duh.
yeah if they went say 20kms per hour they would hardly use any fuel at all ...
That font animation is so smooth
Best explanation ever :)
Before playing the video, I think it's a matter of finding optimal fuel efficiency (and operating costs) instead of shortest travel time.
*When you come out of the storm, you won’t be the same person who walked in. That’s what this storm’s all about.*
this has nothing to do with the video
