My Concorde story: I flew a Cessna 172 into JFK twice about 30 years ago. On one of those flights while on base leg to 13R, I heard a controller instruct an Air France Concorde to hold short for landing traffic. Sure enough, there it was on the taxiway at one o'clock. I was mildly amused by the thought of all those very fast rich people waiting an extra minute for me to land my little four banger. I did my best to make it short and quick, using about one-tenth of the runway to hop off to the GA terminal on the left. Just courtesy. Fond memory.

[@mrxmry3264]

one day i was at hatton cross station when a concorde took off from runway 09R, passing very close to hatton cross station. the engine noise (well, technically it was the jet noise) triggered many car alarms. the concorde left a brown trail of nitrous oxides. i have never seen such a trail behind any other airliner. another time, also at hatton cross, it was dark so i could see that the exhaust gas was so hot it was actually glowing during takeoff and climbout. i don't remember seeing mach diamonds, though. there is a museum in germany where they have a concorde and a tupolev 144. right next to each other.

Virgin is/was a much smaller airline and simply wouldn't have been able to afford it. 2. British Airways was never going to sell its fleet of Concordes for £1 each to one of its major transatlantic competitors. There were some other reasons and no doubt some political pressure on Airbus by Air France.

Vote for Biden, because Trump will probably continue to defund NASA. (Disclaimer: I'm Canadian and can't vote for either.) Speaking to "they already exist"- well, they don't really. Yes, we have supersonic aircraft, but the fuel cost to move more than a couple of people and a dozen bombs faster than sound is exorbitant and prohibitive. Even the military stays subsonic most of the time, just because of the fuel needs. Even ignoring the regulations, just building a new Concorde would result in another plane that costs 12,000$ and a literal ton of fuel *per person* to make a round trip across the Atlantic. (So a round trip on the Concord for one passenger would be dumping 3 months worth of 2022 carbon emissions into the atmosphere in seven hours.) The planes that we can build *right now* are just not acceptable on either a monetary or environmental cost basis. So, there *is* a huge engineering challenge to solve, and the point of the video is that NASA is trying to solve at least part of it. As for the "only used by rich people" - Concorde definitely was that, especially for Air France after the "no overland supersonic flight" rules came in, simply because of the sheer cost of fuel. Ticket prices were insane. Whether new planes like Boom's end up that way will depend on how much the aircraft cost to build and operate, really. If an airline can offer seats on a supersonic plane for similar prices to a subsonic one, then supersonic aircraft could easily replace subsonic on all long-haul routes. And the truth is none of us have anything approaching enough information to judge how much the tickets are likely to cost.

This started out as a project between Boeing and NASA (the US govts. way to sneak in subsidies for the R&D), but Boeing has no customers for a supersonic plane and instead have customers for more fuel efficient engines and Boeing has publicly said they aren't going to develop a new plane until next decade, and this coincides with engines being ready that can replace what they use now.

1:50 A correction and an important clarification. 1) The fastest train, the maglev Chuo Shinkansen, operates at 505 km/h but has reached 603 km/h in testing. The fastest wheeled train was a French TGV that reached 575 km/h. 2) The speed of sound depends on the temperature of the of air. The colder it is, the lower the speed of sound is. At 20 °C the speed of sound in air is 1235.556 km/h. This is why if you divide the Concorde's top speed of 2172 km/h by Mach 2.04 you only get 1064.7 km/h: it travelled at just over twice the speed of sound, but it did so way up in the lower stratosphere where the air temperature is -56 °C.

[@josiah42]

I thought those train speeds looked way too low for Japan.

[@philiphartman2785]

About no. 2. Sound travels faster depending on density, not temperature, although temperature affects density . That is why everything is louder at night, as it gets colder the air becomes more dense. At the lower stratosphere the air is just not dense.

[@JonMartinYXD]

@@philiphartman2785 It is the other way around. "In gases, adiabatic compressibility is directly related to pressure through the heat capacity ratio (adiabatic index), while pressure and density are inversely related to the temperature and molecular weight, thus making only the completely independent properties of _temperature_ and _molecular structure_ important (heat capacity ratio may be determined by temperature and molecular structure, but simple molecular weight is not sufficient to determine it). Sound propagates faster in low molecular weight gases such as helium than it does in heavier gases such as xenon. For monatomic gases, the speed of sound is about 75% of the mean speed that the atoms move in that gas." The temperature of a gas is just the mean kinetic energy of the molecules/atoms, so the mean speed in a monoatomic gas defines its temperature (since the mass of every atom or molecule - depending on the element we are working with - is the same, the kinetic energy boils down to just their speed). Of course the atmosphere is not monatomic so the composition at a particular altitude also affects the speed of sound, but given how well mixed the atmosphere is - at least the parts of it we fly in - the difference it contributes is very very small. If the composition was _very_ different the speed of sound would also depend on its frequency. Some gases (eg. CO₂) cause acoustic dispersion (the equivalent in optics is light undergoing chromatic dispersion when it passes through a prism) and some do not (eg. N₂ and O₂).

[@NicksStuff]

@@philiphartman2785 It *is* the temperature, not the density. Pressure (which changes density) has no impact on the speed of sound in the air

[@QuantumDelta]

@@NicksStuff They're both correct; the medium the sound is travelling through is effected by the density/elasticity and energy(temp/vibration) of the particles the medium is made up of. So temperature will affect it somewhat due to the higher energy in the particles allowing them to bump into eachother more rapidly spreading the noise. Density will also in turn affect the speed because the particles in the medium will also bump in to eachother faster if it's denser. This is why sound travels significantly faster through water, and solid objects, than through air, and doesn't travel at all in a vaccuum.

the sonic boom is not the only problem. you also have very high fuel consumption due to the nature of the engines. a concorde consumed more than 4 times as much fuel per passenger (relative to distance, not flight time) than a 747. that is one reason why concorde tickets were so prohibitively expensive. edit: and let's not forget the noise which is a direct result of the very high exhaust speed required for supersonic flight. there's not much they can do about that.

[@r0cketplumber]

One thing I do miss about not working in Mojave anymore is the sonic booms where I became something of an aficionado, able to recognize the type of aircraft from its boom. T-38s gave quick but low amplitude ba-bangs, F-15s were more authoritative, and the SR-71 gave good a strong one that was often just as staccato as the littler birds because it was so fast. But the Space Shuttle was the granddaddy of them all, providing a powerful slow-paced Ba-BOOM that could knock hardware off our stock shelves. Protecting the shelves from earthquakes to keep them from falling over by attaching struts to the roof made for excitement when the Shuttle bounced the roof like a trampoline. Once after showing some guests the Ez-Rocket in our flightline hangar, I saw a contrail coming our way quickly. "Hey, we might get a sonic boom in a couple minutes," I warned, and they scoffed until we got a nice boom right on cue. Another day at my desk I heard a good loud boom and struggled to identify it. Hmmm, it wasn't bombing on the range at China Lake to the north, nor was it from blasting at the cement plant's quarry three miles away to the west, and it didn't have the usual ba-boom of a sonic boom, what could it be? Then it came again and I realized it was just plain old thunder- it rained so rarely there that when I heard hoofbeats I always thought "Zebras!"

[@aspartam_]

I don't really see it becoming more environmentally friendly than conventional planes because air drag grows exponentially with more speed, but we'll see

[@TheRealDarklight]

It shouldn't. Supersonic flight will pollute drastically more, both because more energy needed, therefore higher fuel consumption, and because it needs to fly higher for lower drag, where the same emission has bigger and longer lasting effect. Going faster, higher, means specialized very expensive low capacity planes. Therefore, prices and per person fuel consumption will be incredibly high. Even if it's quiet, what does it really achieve? In what situation is this really needed or best solution? Can this be ethical? I would argue that even if airlines make it profitable, this only ever be a toy for the rich, on the environment's dime.

[@rjdverbeek]

The wealthiest 1% of humanity are responsible for twice the emissions of the poorest 50% of humanity. Introducing a supersonic aircraft again for the wealthiest only increases this problem. Furthermore, it looks like that NASA is spending public money for making something only a small group of people will benefit from.

It will be worse in both cases. Fairly simple economics and physics.

The high fuel cost was the main reason why the concorde program was cancelled.

Aside from the sonic boom issue, the Concorde was incredibly loud at takeoff. The engines were just LOUD even at low speed, and it generated endless complaints from people living under its flight path near airports.

[@rogermwilcox]

Yeah. That's because in order to have enough thrust to punch through the sound barrier, the engines needed AFTERBURNERS. If you've ever been behind a fighter jet at an air show with its afterburner turned on, you KNOW just how incredibly loud those things can get.

I lived in Alameda California from 1986 - 1989. My apartment was about 3-4 miles from the Oakland airport. The Concord would occasionally fly out of that airport. It had a very distinctive sound from all the other aircraft, so much so that I would look over to the airport if I heard that sound. I saw it 2-3 times. It was very impressive looking. It was easy to distinguish from other aircraft entering or leaving the airport because the nose cone was angled down during takeoff and landing. Incidentally, the Oakland airport was the last airport from where Amelia Earhart (American aviation pioneer and first female aviator to fly solo across the Atlantic Ocean) took off on her fateful flight, never to be seen again. In 1935, Earhart became the first person to fly solo from Hawaii to California.

One thing you didn't mention about the concord, it needs a lot more repair and upkeep than a normal plane. The rising fuel cost (it uses maybe 10 times as much fuel per passenger as a regular jet), and the crash were both key factors, but another, that's rarely talked about is evey few flights back and forth, the plane needed a full overhaul. Not just new oil, but parts needed adjustment and sometimes replacement. It became to hard to keep them ready to fly that they airlines started to carry a spare concord in each airport for when service was needed. Now, I get it. The concord was cool. Fuel usage was through the roof, but we live in a world today where the superrich might be willing to pay $15,000 per ticket, so we could see this return. I like the technology. I think a healthy fuel tax would be prudent too, because we can't ignore high fuel users when trying to address climate change. But I understand why Airlines would be interested. Superfast travel and higher flight altitude are cool. People are going to want this, and I think we probably will see a return of supersonic travel in the coming years/next decade or so.

[@tsubadaikhan6332]

To get the technology required, we may need to burn more fuel at first, but who knows? It all contributes to an increased knowledge base. A new jet engine supplier has pitched an adaptive cycle engine for the F-35 fighter that would mean it could cruise above Mach 1, and use less fuel.

Afterall, exactly how many Concordes do you think were made? Why spout nonsense about a subject you clearly have no knowlegde of? Twonk!

OK, First, I said "Maybe 10 times" - which was clearly an estimate (maybe) . . . and I looked it up. It's 5.5 times more fuel per passenger than a 747 (not 4 times). 2nd, you missed the point about having a spare plane - it's not for "parts". Yes, every plane gets checked frequently, but the concords were deemed unfit to fly and in need of repair a hek of a lot more often. THAT'S why they had a spare plane at every airport, not for parts but as an alternate plane, if the one that landed a few hours ago wasn't ready for it's next scheduled flight. It was the only way to prevent long delays at takeoff. So, you're wrong. I invite corrections, but you're wrong about many things and your tone was uncalled for.

The Concord is probably an example of transitional technology. It makes travel marginally better, but at extreme cost and inconvenience. Most likely by the time we figure out how to mitigate the problem of a sonic boom we'll have suborbital commercial flights that completely side step the problem by being in the zone where the air is virtually non-existent and so sound is not an issue.

Technically, this is fasciniating. But the force of air resistance is directly proportional to the square of the object's speed through the air.

Not for the general public......far to expensive.....only for the rich. The possibility of the plane going into service...near zero. The development cost of the Concord SST was paid by the poor taxpayers. The poor people paying for toys of the rich.

[@StevenPine-s8t]

GREAT VIDEO!!!! I love Cleo's enthusiasm!!!

[@aurtisanminer2827]

The craziest fact about the concorde was that it went so fast that friction from air caused it to heat up and cause a ton of thermal expansion that they had to engineer the plane around.

[@badraven9532]

And a resultant fun fact was that "cold" in the hangar it leaked fluids like a 60's british motorbike, and stood there with numerous drip trays placed under it.

[@thethingthatshouldnotbe3035]

I love how excited you get talking about this stuff, it makes it soo incredibly fun to watch!

[@Finnix.]

One thing Im sad you didnt talk about was the fuel consumption, because the problem with the supersonic flight is not only the noise but also the insane fuel usage that removes these airplanes from being competitive. The airlines really do care a lot about fuel as even a few percentages of less fuel consumption can increase the revenue of the company... Did NASA talk about that in any way or is that just a problem for later? (If Im wrong and supersonic flight is absolutly fuel efficient please correct me)

[@symix.]

Its not as fuel efficient as normal jets, but if they charge a lot more, they can be profitable. Businesses/rich people can afford it, not everyday joes going for holiday.

[@berndeckenfels]

NASA doesn’t really care about business viability,, but then again it’s not a nasa project anyway.

[@jttech44]

It's much more likely that if this gets off the ground it'll be private jets, not commercial airliners.

[@michaelc3977]

Fuel consumption wasn't as bad as you think. Concorde only used about 4 times the amount of aviation fuel as a 747 to cross the Atlantic. Take-off was where she was thirtsy. The engines were incredibly efficient at the speeds she achieved and she had to be throttled back when she reached mach 2.0 because she wanted to keep accelerating.

[@alonzoaftee]

Cleo, this is your best episode yet. I’m old enough to remember sonic booms when were outside at recess. The moment the boom was heard, every little kid stopped what they were doing and looked up trying to find the plane. Great memory from my childhood. Thanks.

[@TheJeffreyhowell]

Cleo, I love your energy! As a part of the X-59 team, I really enjoyed your content!

[@Dani-ln6sp]

Goosebumps, feels like it's uniting humanity in our common quest to explore and reach beyond what was previously thought possible

[@Dr.K.626]

Constantly amazed where you get to go into and what you get to see. It's a tribute to the respect you and your channel garners.

[@BenLovejoy]

Flying on Concorde was one of the most memorable experiences of my life. Not sure I'll manage another supersonic flight on one of the coming aircraft, but I live in hope!

[@trespire]

Small correction @1:57, the fastest train (running on conventional tracks) is 574,8 kph by an Alstom TGV in France.

[@Bellabong]

It was a special AGV/TGV hybrid. Not a "production model".

[@breakbollocks9164]

@@Bellabong - So what? Jealous? Yep, French engineering is generally quite a bit ahead of that in the exceptional country.

[@BooBaddyBig]

@7:20 Concorde DIDN'T actually have gas-guzzling engines. They were actually about the most efficient aeroengines ever fitted to any commercial airframe, ever. The reason was they got extra compression from the air inlets, as well as from the compressor sections, so they ran extremely hot and so thermodynamic efficiency was world-beating. At low speeds they were still inefficient, but Concorde mostly flew at M2. And the aircraft as a whole was relatively inefficient, but that's because it was a heavy plane, supersonic, and a delta wing. Any new plane can't be expected to become magically more efficient. They'll be better, but not nearly as efficient as subsonic aircraft.

[@MrCaiobrz]

You could have summed this up byu simply telling what they really were. Air-breathing rockets.

[@BooBaddyBig]

@@MrCaiobrz Nah, they were just turbojets. Actually rockets are jet engines, and not the other way around, because they're propelled by jet propulsion.

[@michaelc3977]

@@BooBaddyBig As the son of a Concorde engineer it's great to hear someone else correcting the false information surrounding this video. Bravo.

[@chrisreilly1290]

3:50 love the dude who makes the rocket carts

[@Dennis-uc2gm]

Your grandfather was one of those slide rule guys that NASA's foundation is built on. They did what most people said was impossible or at least very difficult at the time. The future looks exciting for NASA and our country once again. I remember the sonic booms in the 60's when I was a kid and all of those were from military aircraft. It will be nice to see air transportation returning to mach speeds in the future.

[@doop6995]

dont tell me what my grandfather was, you didnt know him!

[@donaldculp3759]

Wow! What a jerk response. My Dad was a slide rule engineer for NASA and I'm proud. He also helped save Apollo 13. Crew cut WWII pilot of B-17. Old school

[@Dennis-uc2gm]

What I admire the most is those guys is they had to think. Yeah that piece of plastic was an aid, but you had to put the decimals in the right place and know all the constants and you did most of it in your head. In there case they HAD to be right most of the time.

[@hagridt4334]

This is very interesting. Mainly because where i live (Poland) there was information on the news that they found microscopic cracks on the wings, so the plane was grounded for investigation of the problem. After few monts there was new info that they won't fly anymore because they can't pinpoint the source of the problem and it could be to dangerous to keep them flying.

[@benayers8622]

oooh

[@k3corvette35]

I got to see the Concorde take off out of NYC and hear the sonic booms and it was truly impressive! It was truly depressing when they got retired and felt like we went backwards as far as aviation goes !

[@arymate]

It made me really ponder on how your grandpa worked for NASA years ago. It well and truly sounds awesome to hear that from a wonderful content creator. Thanks for everything, Cleo - I really love how curious and ecstatic you are when it comes to science and technology. May your grandfather rest in peace. 😊❤

[@texasgrandpa6266]

In addition to the noise, the sonic boom created a sound wave (just like thunder) that would cause vibrations that rattled windows, etc. As a child in the ‘60’s on the east coast we would occasionally hear and feel the effects of sonic booms created by military aircraft.
