Sorry to nitpick but at 4:30 you somewhat imply that XF-84H "Thunderscreech" was an early attempt at supersonic flight before jets. But Thunderscreech first flew in 1955 almost a decade after F-86 and Bell X-1 both jet and rocket powered aircrafts achived supersonic speeds. Around 1955-56 early YF-104 were already reaching mach 2.2 speeds.

The Republic XF-84H Thunderscreech, while an interesting and unusual airplane, was developed and built well after the Bell X-1 had crossed the sound barrier. It was also designed as a carrier based aircraft with no requirement for a catapult. The way it is placed in the video makes it sound like its design goal was breaking the sound barrier, which it wasn't.
There is a massive omission in the 'documentary'. What is missing is exactly what the Americans learned from Miles Aviation. The answer is simple. As an aircraft approaches supersonic speed, the air flowing over the control surfaces, the ailerons and elevators, begins to establish pressure fronts that move back along the wings surface. These fronts do not advance at the same speed, so when they pass where the ailerons or elevator hinges are positioned, the surface pressure can be very different above and below the control surface. This change in pressure result in the control surfaces moving with such force a pilot cannot withstand the pressure and the aircraft can go out of control and possibly break up due to the violent oscillation set up by the uncontrollable surface pressure. The British had learned this and had built 'fully flying' control surfaces to replace the traditional elevators, which are much more susceptible to the problem. The Americans quickly changed the design of the Bell X-1 to have fully flying elevators mounted on the vertical stabilizer fin. You can see this in the videos. The earlier glide and low speed flight aircraft clearly have traditional elevators, the hinges being clearly visible. The later ones do not. If you look closely, you can see the plate against the vertical fin, to which the 'fully flying' control surface is mounted. The plate rotates and this causes the 'fully flying' wing to rotate with it. It is ironic that the X-1 in the museum may be the one that Yeager broke the sound barrier in, but it has either been modified back to the original configuration, with elevators hinging on the fixed horizontal stabilizer, or it is not the correct airframe but a substitute, hiding the crime of stealing British technology. What is also lame about the Yeager record was the use of a rocket motor. First small ones and then ever larger and more powerful ones. The delays that hurt Miles Aviation was the development of the British jet engines. The first flights were made with a less powerful substitute when the planned engine was not ready in time. Once the larger engine became available, Captain Eric "Winkle" Brown quickly proved the Miles M52 was easily able to exceed the speed of sound, but using a British jet engine. This was something the "X" series of aircraft were not able to accomplish for years, despite the British still, stupidly in my opinion, sharing jet engine technology with the US companies that began building jet engines under a "free" license from Churchill!
The all moving stabilizer was not a British invention, nor was it a British invention to use it for supersonic flight and it was already being seen on the XP-86, in development at the same time. There is little evidence for this British conspiracy theory, past the claims of sore losers. The Bell visit to Britain is not even confirmed to have ever happened.

My Grandfather flew with Sir Charles Kingsford Smith when he was about 12 years old in the Southern Cross. He later went on to become a mechanic working for Qantas and Ansett. As a child in the late 1970s I remember going to someone’s house in Sydney who was a family friend who had also worked in the airlines. He had two huge concord models in a collection of models - each about 1.5 - 2 metres long. They were old and dusty but still in relatively good shape. They were on stands and looked like the sort of thing you’d see in a museum. They had the branding of Qantas on them, flying kangaroo on the tails and all. Turned out the back story was Qantas had committed to purchasing Concords in Australia due to our vast country and long distance between cities. However Boeing rushed in and scuttled the contract by underselling Concord at the 11th hour. The 747 was much loader and slower, but could carry many more passengers. The was a lot of public and political pushback about the sonic boom so in the end it was an easy decision. Both the concord and 747 were released in 1969 so the race was on to get fleet sales. The first 747 flew in Australia in 1971… the concord then flew to Sydney in 1972 as part of their global sales tour, coming in from Darwin in just 2 hours (the same flight still takes over 4 hours today)… almost in a ‘Look at what you missed out on’ type of moment. But the horse had bolted and rest is history... So the concord models had been destined for the bin, had been rescued and ended up at this suburban house in Sydney. I wonder where they are today? Australian aviation history!

Fun fact about the SR-71: Mach 3.2 is only the unclassified top speed of the plane. There is much unofficial talk that it can go much faster. An SR-71 pilot I met on a museum tour was very cagey about the fastest he'd ever flown. Additionally, despite the fact that the planes are retired, not all aspects of its design have been declassified. Bonus fact: due to thermal expansion when it was at speed, the SR-71 is built with gaps in its body and wings. The plane had to be fueled directely on the runway because it would leak jet fuel until it reached an appreciable portion of the speed of sound and the gaps closed up.
it did not get refueled on the runway, Col. Richard H. Graham's book busts that myth, they refueled like normal on the ground and then would taxi to the runway and take off. They leaked, but they didn't leak nearly that much.
If its not anything official than it merely a theory without anything conclusive. If it was able to go faster it wont be by very much and it would be able to do it for a small amount ot time before its engines amd fuselage arent able to withstand the stress and temperatures. The mig 25 was able to reach mach 3.2 but if it maintained such a speed for more time than what engines and frame allow, then it would be permanently damaged.
This should have just been called “flying faster then the speed of sound” because most of it is basically the history of faster than the speed of sound
You left out about Albert Scott Crossfield. He was an American naval officer and test pilot. In 1953, he became the first pilot to fly at twice the speed of sound. Crossfield was the first of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the United States Air Force and NASA.
2:02 The speed of sound in air is primarily dependent on temperature, rather than pressure. The reference to sea level is misleading, as it suggests a constant temperature, which is not accurate. Specifically, a speed of 1225 kph corresponds to an air temperature of 15 degrees Celsius.
The reason why we gave up to commercial supersonic flight is because internet became better and there was no need for as much "IN PERSON" meeting. And thus flight time isn't a lost time anymore. Plus it's super inefficient.
@@DrumToTheBassWoop that's not the time it takes. It's 2-3h for London to new York. And that was with a ticket price of 10k. Nobody cares about SS flight nowadays except maybe Influencer who can make video out of it
It's a shame you didn't mention Avro Arrow made in Canada. It was the first unofficial level supersonic flight and also Lead to the use of Delta wing technology.
The Arrow's first flight was in March 1958, years after supersonic flight was a reality for military aircraft and delta wings were not unusual by then. For example, the F-102 Delta Dagger was actually in service by 1956, having first flown in 1953.
(Detailed comment) This video skipped three vital FACTS. 1) Tupolev DID steal most of Concorde's plans. 2) There is no mention of the Ogival Delta Wing that made Concorde fast and more importantly smooth through the sound barrier. 3) AIRBUS was the response to the behaviour of both America and the Soviet Union in this era by European nations, who grew sick of the depravity of companies like Boeing, and just how far they would go for a monopoly on success. Sound eerily familiar still today? Now modern purveyors of sonic flight have a lie to get around with the public and experts that still live. After destroying Concorde's innovation with lies (time would have made engines quieter, more fuel efficient, whilst safety would have only improved anyway), the myth of 'dangerous' sonic booms will plague any company trying to go back in time to undo the sheer injustice that Britain faced throughout the twentieth century. Theft and espionage built Boeing, Tupolev and others into national giants. The only channel that has been truly 'diplomatic' on this subject so far was Mentour Pilot. Airbus is granted to us through Karma, as is the downfall of Boeing. They deserve all they get. I want to see any real evidence of the 'harm' of sonic booms, when people were told anything from seizures and vomiting, to building damage. I have seen hundreds of videos on this topic, and yet I am yet to see a single one that documents evidence of this. Come on Coldfusion, your channel is better than this. Everything I have stated is also public knowledge, except the conspiracy to make sure the Boeing 747 was not touched in her lifetime by supersonic flight. (The U.S redacts uncomfortable truth). As I began, it's more than coincidence that now that aircraft's life has ended, people can't move fast enough to revisit supersonic travel again. OR is it because Boeing no longer holds such power over the American government to stop it?? The truth is always out there.
Now now, you don't want Boeing to pay a 3 letter agency to unalive you like they did with john barnett, now do you? Stop it, no one will uncover the sheer incompetence and ill will of that company, because they are a military contractor and any attack on them is an attack on military industry
The video generally glosses over quite a few things or implies things that aren't true. That said, supersonic booms are loud and can, if you're unlucky, carry extremely well and it is still a shockwave - meaning it carries force. The thunderscreech in particular causing sickness is documented, but that's a unique case. The main issue is still cost. What we're currently seeing is a bunch of techbros convincing everyone that supersonic travel would be sick, but it just isn't efficient and with the current inflation and rise in energy cost in the west, it just isn't realistic. Aircraft at Mach 0.8 are the cheapest way to move people in reasonable time frames, so that's where it's going to stay. If we find a way to reduce the cost of operating these aircraft (cheaper fuel), we MIGHT make an economic case for supersonic flight - but the way the world is going, that's not going to happen.
Thanks Dagogo! Great job as always! I’ve been keeping a close eye on this stuff. Been an aviation nerd since I was 4. A large number of the Boom team seems to be former colleagues of mine, and they set the groundwork for the X-59 design. They are the team to watch in my mind.
IMO what killed Concorde and supersonic commercial flight are several things: Because of telecommunication there is really no need to get to New York (or the other way round) in three hours. And in reality to get through the airports you need four hours plus three hours to get to/from the city center. Secondly flying is no longer glamorous or fun if you do not fly First or Business and if you fly those then that can be (an certain airlines at least) so much fun that you don't want that to end in three hours, you'd rather enjoy the luxury and pampering for the whole day as the day is wasted anyway. There are many more who can afford many times higher ticket prices than what Concord charged and had capacity for but those people are not in a hurry and they want to pay for luxury, not speed.
ColdFusion delivers one of the most stunning swift overviews of the flight industry. It left me speechless a couple of times. The historical video kept me speechless, the great info seated. I'm not really fond of flights, but the history and it's touch on today's approach is unmistakable. As of the final question - I don't think it will be available any time soon, the energy(fuel) consumption is just too great. But I look forward to see further development in this field. I don't care if they are British, French, or US. It would be amazing to see the limitations of the technology moved forward.
@@Axicab no - it wasn't a 'cheap shot' at all. Boeing was in it's 6th year since the MD merger... aka; the beginning of the end for Boeing quality. That 'cheap shot' is quite justifiable -- Boeing 'EARNED' it. Lockheed needs to take over and let the engineers run the company and get rid of the pencil necks.
guys is that a Big company or television program or news aggency ? Because i am following ColdFusion very very long time ago they didnt even had 2m subs yet. But this channel improved my knowladge of many different things. you guys really deserve award or something like that.
What? Who is wanting to substitute supersonic travel for internet or work? I recently spent 10.5 hours on a plane one way. I would have paid much more to cut that in half.
FireMunki you basically just called passenger flights a niche market though. Anybody that flies even slightly often would want it to be quicker. Nobody wants to be middle seat beside some big dude crunching doritos any longer than they need to
It makes sense. Concord was only retired due to how the fuel tanks were not “armored” well and the tires had a frequent chance of tires bursting…and the tail also had a very odd tendency for its tail to fall apart mid flight.
"The Americans took British data but did not reciprocate." No surprise there; US culture is still too young to have developed integrity and common decency. Those things take centuries. 🤷♂
I was one of the lucky ones to fly on the Concord on its last flight in 2003. It was an experience but one I would not use on a routine trip if they where still around. The seats where very uncomfortable, the space for legs was tight for a 6.4 foot guy like me. No TV sets, the lighting was not very good and the noise even inside was just ear popping loud. It was a very short flight which was long enough for me. I would of gone nuts if I had to fly in that dustbin between say Heathrow and New York JFK.
Thank you Dagago for educating us with yet another brilliantly researched documentary - much appreciated. Having flown on more than 1,000 international flights, I quite enjoy flights of 8-10 hours duration. The 17 hour direct flights I took from Singapore to NYC were far too long. I foresee supersonic passenger flights however at what cost, per ticket? Concorde flights were very expensive, partly because of the cost of fuel per passenger. The tickets were affordable for senior corporate and wealthy passengers alike, but not for the average person. I predict that supersonic flight will always remain as exclusive & expensive.
I tried studying the race to supersonic several times when I was living at home yet all I ever came across was the story of that darned letter to the Rolls Royce staffers and other such anti-american propaganda by the British. I'll have to watch this several times to absorb the truth and throw out all the nonsense I learned previously. 👍 Awesome Saucem!
The big mistake with the Boeing 2707 was the decision that it should fly at mach 3. That's unrealistic, even supersonic jet fighters like the F-15 can only get up to about mach 2.5.
The DC8 was worthy of a mention- the first commercial airplane to fly supersonic back on '61. No other commercial airplane maker at that time had the balls to pull that stunt with one of their planes...
Henri Coanda was a Romanian inventor ,is the creator of the first jet aircraft in the world which he tried himself in 1910 at Issy-les-Moulineaux (France)!!!

I usually expect extremely high-quality videos from this channel but this one feels off. It’s almost like it was written by chatGPT and rushed out. It was still good, but doesn’t seem quite right.
The US govt intentionally caused the shutdown of the Avro Arrow in Canada and most likely this project in the UK. The reason was that nobody was allowed to build a better plane than the USA or they would lose air superiority. And the Arrow was light years ahead of the US planes. Any plane that met that criteria was cancelled at the demand of the USA.
The crash site of that Concorde accident is interesting, because its just a few kilometers away from the place the Tupolev Tu-144 crashed 27 years prior at the Paris Air Show. So the two crashes that effectively ended the only 2 commercial supersonic aircraft happened at the same place.
24:39 can you really go pass Mach 1 without making a sonic boom? Sound is pressure moving through the air, right. Above the certain speed a sound wave becomes a shockwave. Basically an explosion. A boom
@@Global_Optimizationyou could fly at higher altitude where the air is thinner. How would you make the release of energy less destructive at commercial jet altitude. You can change the length of the shockwave, I guess. But you still have to deal with the force behind it, right?
First human flight was not 1903 - that was the first *powered* flight. People had been flying gliders for a couple decades prior to that (e.g. Otto Lillienthal).
@@sirBrouwer This was all Classified to the USA - after all only last year did we finally crack the research tree topic of how to detect 225+ year old technology of Aerial balloons and how to shoot them down. I am so proud of my country.
Hans Von Ohain of Germany was the designer of the first operational jet engine, with the first prototype aircraft, the Heinkel HE 178, first flying in 1939. However, credit for the invention of the first jet engine went to Great Britain’s Frank Whittle, who registered a patent for the jet engine design in 1930 but, did not perform a test flight till 1941. Honestly, he probably would have been first but the British government was overly skeptical and delayed its development. Us in the U.S. flying our first jet aircraft the Bell P-59 Airacomet powered by two GE J-31 jet engines.
Read first hand accounts. Like the genocidal powers that succeeded the Nazis, the Nazis blackmailed the scientists. Threatening to kill entire families if they failed. North Korea style pressure. But that’s why these scientists preferred to flee west to the US than to the Soviet Union. Under the Soviet Union they’d be under the same treatment.

The first 747 flew in Australia in 1971… the concord then flew to Sydney in 1972 as part of their global sales tour, coming in from Darwin in just 2 hours (the same flight still takes over 4 hours today)… almost in a ‘Look at what you missed out on’ type of moment. But the horse had bolted and rest is history... So the concord models had been destined for the bin, had been rescued and ended up at this suburban house in Sydney. I wonder where they are today? Australian aviation history!
Man do you ever make a video that isn't entertaining and educating?? Best content on RUclips!
Also thanks to his British Australian accent
Way, way more than 1 person makes these.

The narrator has mentioned many times for many years that he doesn't do it alone and has a "team". I can't tell you if they were his employees or independent contractors. Unless a public company bought his stuff I don't know how you would know or to whom it's been sold. It's garbage now though.
"You aren't big enough and there aren't enough of you to get me in that thing again." -- XF-84H test pilot to XF-84H project engineer
Fun fact about the SR-71: Mach 3.2 is only the unclassified top speed of the plane. There is much unofficial talk that it can go much faster. An SR-71 pilot I met on a museum tour was very cagey about the fastest he'd ever flown. Additionally, despite the fact that the planes are retired, not all aspects of its design have been declassified.
Bonus fact: due to thermal expansion when it was at speed, the SR-71 is built with gaps in its body and wings. The plane had to be fueled directely on the runway because it would leak jet fuel until it reached an appreciable portion of the speed of sound and the gaps closed up.
What was the fastest he flew?
it did not get refueled on the runway, Col. Richard H. Graham's book busts that myth, they refueled like normal on the ground and then would taxi to the runway and take off. They leaked, but they didn't leak nearly that much.
If its not anything official than it merely a theory without anything conclusive.
If it was able to go faster it wont be by very much and it would be able to do it for a small amount ot time before its engines amd fuselage arent able to withstand the stress and temperatures.
The mig 25 was able to reach mach 3.2 but if it maintained such a speed for more time than what engines and frame allow, then it would be permanently damaged.
I prefer the idea of a 10 day blimp trip rather than a 30 min hypersonic passenger flight.
Great video! Keep producing videos which peak your interest, keeps them authentic and thought provoking.
What a superb video,I witnessed a sonic boom in 2013 and it’s something I’ll never forget, cheers DAGOGO really enjoyed it 👍
This should have just been called “flying faster then the speed of sound” because most of it is basically the history of faster than the speed of sound
You left out about Albert Scott Crossfield. He was an American naval officer and test pilot. In 1953, he became the first pilot to fly at twice the speed of sound. Crossfield was the first of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the United States Air Force and NASA.
Love the new direction, but still with the same super high class of production. We expect no less - fortunately for us you always deliver...
Amazing work as always, thank you Dagogo!
2:02 The speed of sound in air is primarily dependent on temperature, rather than pressure. The reference to sea level is misleading, as it suggests a constant temperature, which is not accurate. Specifically, a speed of 1225 kph corresponds to an air temperature of 15 degrees Celsius.
The reason why we gave up to commercial supersonic flight is because internet became better and there was no need for as much "IN PERSON" meeting. And thus flight time isn't a lost time anymore.
Plus it's super inefficient.
I dont know dude, imagjne being in Sydney ftom london in two hours.
@@DrumToTheBassWoop that's not the time it takes. It's 2-3h for London to new York. And that was with a ticket price of 10k.
Nobody cares about SS flight nowadays except maybe Influencer who can make video out of it
Maintenance cost and fuel costs is the reason.
Face to face meetings are absolutely still a thing. That’s why business jets market is huge.
It's a shame you didn't mention Avro Arrow made in Canada. It was the first unofficial level supersonic flight and also Lead to the use of Delta wing technology.
The Americans did Canada so dorty with that program... And it's often overlooked sadly.
@@MeatyZeegwe do everyone dirty somehow
I was sad there was no mention of the Arrow either :(
The Arrow's first flight was in March 1958, years after supersonic flight was a reality for military aircraft and delta wings were not unusual by then. For example, the F-102 Delta Dagger was actually in service by 1956, having first flown in 1953.
I'm so glad you're finaly covering an aerospace topic!
We've always watched sonic booms on RUclips but never thought of the history..
thank you .. sami&isaac
Could honestly listen to you commentate the grass growing.
Such a great video, thanks guys!!!
That would've made an amazing April's first video. I bet he would've made it accidentally entertaining and educative though.
Keep posting. Learning so much from your channel. Thanks.
(Detailed comment) This video skipped three vital FACTS. 1) Tupolev DID steal most of Concorde's plans. 2) There is no mention of the Ogival Delta Wing that made Concorde fast and more importantly smooth through the sound barrier. 3) AIRBUS was the response to the behaviour of both America and the Soviet Union in this era by European nations, who grew sick of the depravity of companies like Boeing, and just how far they would go for a monopoly on success. Sound eerily familiar still today? Now modern purveyors of sonic flight have a lie to get around with the public and experts that still live. After destroying Concorde's innovation with lies (time would have made engines quieter, more fuel efficient, whilst safety would have only improved anyway), the myth of 'dangerous' sonic booms will plague any company trying to go back in time to undo the sheer injustice that Britain faced throughout the twentieth century. Theft and espionage built Boeing, Tupolev and others into national giants. The only channel that has been truly 'diplomatic' on this subject so far was Mentour Pilot. Airbus is granted to us through Karma, as is the downfall of Boeing. They deserve all they get. I want to see any real evidence of the 'harm' of sonic booms, when people were told anything from seizures and vomiting, to building damage. I have seen hundreds of videos on this topic, and yet I am yet to see a single one that documents evidence of this. Come on Coldfusion, your channel is better than this. Everything I have stated is also public knowledge, except the conspiracy to make sure the Boeing 747 was not touched in her lifetime by supersonic flight. (The U.S redacts uncomfortable truth). As I began, it's more than coincidence that now that aircraft's life has ended, people can't move fast enough to revisit supersonic travel again. OR is it because Boeing no longer holds such power over the American government to stop it?? The truth is always out there.
Now now, you don't want Boeing to pay a 3 letter agency to unalive you like they did with john barnett, now do you?
Stop it, no one will uncover the sheer incompetence and ill will of that company, because they are a military contractor and any attack on them is an attack on military industry
The video generally glosses over quite a few things or implies things that aren't true.
That said, supersonic booms are loud and can, if you're unlucky, carry extremely well and it is still a shockwave - meaning it carries force. The thunderscreech in particular causing sickness is documented, but that's a unique case.
The main issue is still cost. What we're currently seeing is a bunch of techbros convincing everyone that supersonic travel would be sick, but it just isn't efficient and with the current inflation and rise in energy cost in the west, it just isn't realistic. Aircraft at Mach 0.8 are the cheapest way to move people in reasonable time frames, so that's where it's going to stay. If we find a way to reduce the cost of operating these aircraft (cheaper fuel), we MIGHT make an economic case for supersonic flight - but the way the world is going, that's not going to happen.
He does it EVERY VIDEO@@zibingotaeam3716
w video i used this for my school project bc this vid has soooo much info
Hey @ColdFusion
Little error at 16.13 "mach 2.44", I think you meant "1.44"
Also on the screen at the time: Manurer instead of maneuver
Dope Content Cold Fusion 🤘🏼😎💯💧
Cold Fusion Class on a Easter 🐣 Sunday & I now get a great 30 minute break👍😊
Very nice documentary about aircraft ,I like your voice too
Sad that you missed the oportunity to talk about the MiG 31, the fastest fighter jet ever build, still in use after more than 40 years.
Thanks Dagogo! Great job as always! I’ve been keeping a close eye on this stuff. Been an aviation nerd since I was 4. A large number of the Boom team seems to be former colleagues of mine, and they set the groundwork for the X-59 design. They are the team to watch in my mind.
I wouldn’t say Concorde retired because of the crash? 9/11 had a bigger impact on its retirement, and airbus not wanting to keep making spares for it
IMO what killed Concorde and supersonic commercial flight are several things:
Because of telecommunication there is really no need to get to New York (or the other way round) in three hours.
And in reality to get through the airports you need four hours plus three hours to get to/from the city center.
Secondly flying is no longer glamorous or fun if you do not fly First or Business and if you fly those then that can be (an certain airlines at least) so much fun that you don't want that to end in three hours, you'd rather enjoy the luxury and pampering for the whole day as the day is wasted anyway.
There are many more who can afford many times higher ticket prices than what Concord charged and had capacity for but those people are not in a hurry and they want to pay for luxury, not speed.
ColdFusion delivers one of the most stunning swift overviews of the flight industry.
It left me speechless a couple of times. The historical video kept me speechless, the great info seated. I'm not really fond of flights, but the history and it's touch on today's approach is unmistakable.
As of the final question - I don't think it will be available any time soon, the energy(fuel) consumption is just too great. But I look forward to see further development in this field. I don't care if they are British, French, or US. It would be amazing to see the limitations of the technology moved forward.
that dig at Boeing was gold
Cheap shot at a company that was great back then
@@Axicab no - it wasn't a 'cheap shot' at all. Boeing was in it's 6th year since the MD merger... aka; the beginning of the end for Boeing quality. That 'cheap shot' is quite justifiable -- Boeing 'EARNED' it. Lockheed needs to take over and let the engineers run the company and get rid of the pencil necks.
guys is that a Big company or television program or news aggency ? Because i am following ColdFusion very very long time ago they didnt even had 2m subs yet. But this channel improved my knowladge of many different things. you guys really deserve award or something like that.
Cold Fusion is one of my favorite channels 😍 I will never skip the ads!!
Same....
Great video,as always. I liked that Boeing quip. Nice one.
This was so interesting. So cool how coldfusion covers unique tech documentaries in his own style and the music 🔥🔥🔥so unique!
Great content and one of the best narration voices on RUclips. Is the accent local to a particular location in Australia?
You only need to travel so fast. With the internet and home offices there really is zero need for ultra fast travel. Its a niche market now.
What? Who is wanting to substitute supersonic travel for internet or work? I recently spent 10.5 hours on a plane one way. I would have paid much more to cut that in half.
What ever!
FireMunki you basically just called passenger flights a niche market though. Anybody that flies even slightly often would want it to be quicker. Nobody wants to be middle seat beside some big dude crunching doritos any longer than they need to
Great content Dagogo! Always interesting and in-depth your videos....
You make the most incredible, thoughtful, educational, and well executed content. Thank you for all you do! Keep it up!

Great episode and a welcome change.. thank you.
Small pronounciation tip: "Hee Ny" Dittmar has it's vowels the other way around, as in "High Knee" Dittmar. Heini is the abbreviation of Heinrich.
Chuck Yeager was an absolute pioneer & most daring of daredevils
Absolutely!
The fact you can't say Hitler on a history documentary on youtube is a Cold Fusion topic in itself.
Great video! I love your videos❤
It’s so funny seeing all this hypersonics stuff hit mainstream when I lucked into working on them when I was 18, 13 years ago
I love your videos, the quality and information is stunning. Also, love your calming voice! :D
It makes sense. Concord was only retired due to how the fuel tanks were not “armored” well and the tires had a frequent chance of tires bursting…and the tail also had a very odd tendency for its tail to fall apart mid flight.
I really love these longer, more in-depth videos. I really hope you have the time/ability to keep making them in the future :)
Love this video. This feels like classic Cold Fusion. Just need more eerie music 😅
Interesting
Thank you for your insight and videos
Thought I wouldn’t be interested in this at all, but this guy somehow makes the topic fascinating
"The Americans took British data but did not reciprocate."
No surprise there; US culture is still too young to have developed integrity and common decency. Those things take centuries. 🤷♂
If your urban centers are filled with basketball players, your societies don't get very far.

Always challenging my mind and expanding perceived reality. Thank you for sharing 😊
I have had the Greatest honor to meet several of these fearless pilots.
General Yeager.
Scott Crossfield.
Al White.
I was one of the lucky ones to fly on the Concord on its last flight in 2003. It was an experience but one I would not use on a routine trip if they where still around. The seats where very uncomfortable, the space for legs was tight for a 6.4 foot guy like me. No TV sets, the lighting was not very good and the noise even inside was just ear popping loud. It was a very short flight which was long enough for me. I would of gone nuts if I had to fly in that dustbin between say Heathrow and New York JFK.
Thanks for a fun and well done video.
..from a former airline pilot who flew much slower, at 0.78 Mach :)
Thank you Dagago for educating us with yet another brilliantly researched documentary - much appreciated.
Having flown on more than 1,000 international flights, I quite enjoy flights of 8-10 hours duration.
The 17 hour direct flights I took from Singapore to NYC were far too long.
I foresee supersonic passenger flights however at what cost, per ticket?
Concorde flights were very expensive, partly because of the cost of fuel per passenger.
The tickets were affordable for senior corporate and wealthy passengers alike, but not for the average person.
I predict that supersonic flight will always remain as exclusive & expensive.
You enjoy 8-10 hours of flights? Yikes, kill me now! I get to antsy over about 4 hours.
So Boeing planes are literally falling out of the sky and they want me to try their super super sonic new airplane? No man I’m good!😂
Another very interesting video. Keep up the excellent work!
"A certain crazy man" ... well done demonetization avoidance
My man Dagogo is one of the few creators for who I watch most ad spots.
Well, that was a great video!!
Thanks for covering this fascinating topic!
Storytelling master! Great video, love the history of technology
I hated History subject 😂 but seeing it is related to engineering and technology i am hooked up
Love this content. Thanks for something a little different.
I get so hyped when I see a coldfusion notifications. He makes these videos so digestible.
04:06 Definitely headache inducing even at low volume ,
I can't imagine what this same sound can do at louder volumes.
Always well done I learn something every time I watch your videos
I tried studying the race to supersonic several times when I was living at home yet all I ever came across was the story of that darned letter to the Rolls Royce staffers and other such anti-american propaganda by the British.
I'll have to watch this several times to absorb the truth and throw out all the nonsense I learned previously. 👍
Awesome Saucem!
The big mistake with the Boeing 2707 was the decision that it should fly at mach 3. That's unrealistic, even supersonic jet fighters like the F-15 can only get up to about mach 2.5.
The DC8 was worthy of a mention- the first commercial airplane to fly supersonic back on '61. No other commercial airplane maker at that time had the balls to pull that stunt with one of their planes...
Superbly well presented and informative video as always, professional quality. Respect from the North of England. More please 👍👍
So great to see a video where "tech" does not automatically equate to apps on a mobile phone.
10:55 - "the british got nothing in return" - and therefore neither did the Soviets.
Henri Coanda was a Romanian inventor ,is the creator of the first jet aircraft in the world which he tried himself in 1910 at Issy-les-Moulineaux (France)!!!
Afrer bruising my ribs and recovering from coughing... i could not imagine the pain that dude went through to clench for g forces and shunt blood around the body.
What a G.
Whats the music from 6:49, does anyone know? I checked all of Dagogo's songs but its not there.
i would also love to know!
I usually expect extremely high-quality videos from this channel but this one feels off. It’s almost like it was written by chatGPT and rushed out. It was still good, but doesn’t seem quite right.
I've been getting that feeling more and more often recently. Not sure what's going on.
I remember watching TU-144 flying. It's really loud.
The US govt intentionally caused the shutdown of the Avro Arrow in Canada and most likely this project in the UK. The reason was that nobody was allowed to build a better plane than the USA or they would lose air superiority. And the Arrow was light years ahead of the US planes. Any plane that met that criteria was cancelled at the demand of the USA.
The crash site of that Concorde accident is interesting, because its just a few kilometers away from the place the Tupolev Tu-144 crashed 27 years prior at the Paris Air Show. So the two crashes that effectively ended the only 2 commercial supersonic aircraft happened at the same place.
Not a coincidence, unless proven otherwise.
Hard to believe that engineers didn't look closer at falcons in a stoop.
They sweep their wings back to come down like a thunderbolt.
24:39 can you really go pass Mach 1 without making a sonic boom? Sound is pressure moving through the air, right. Above the certain speed a sound wave becomes a shockwave. Basically an explosion. A boom
This is correct. There will always be shockwaves. The question is how big/loud they are
@@Global_Optimizationyou could fly at higher altitude where the air is thinner. How would you make the release of energy less destructive at commercial jet altitude. You can change the length of the shockwave, I guess. But you still have to deal with the force behind it, right?
First human flight was not 1903 - that was the first *powered* flight. People had been flying gliders for a couple decades prior to that (e.g. Otto Lillienthal).
True, history of aviation is just awesome with people like fokker lillienthal langley!😊
The first flight was done by the Montgolfier brothers all the way back on 21 Nov 1783 with a hot air balloon.
@@sirBrouwer This was all Classified to the USA - after all only last year did we finally crack the research tree topic of how to detect 225+ year old technology of Aerial balloons and how to shoot them down. I am so proud of my country.
Outstanding episode. Thank you!
Then came the Germans.
Hans Von Ohain of Germany was the designer of the first operational jet engine, with the first prototype aircraft, the Heinkel HE 178, first flying in 1939. However, credit for the invention of the first jet engine went to Great Britain’s Frank Whittle, who registered a patent for the jet engine design in 1930 but, did not perform a test flight till 1941. Honestly, he probably would have been first but the British government was overly skeptical and delayed its development. Us in the U.S. flying our first jet aircraft the Bell P-59 Airacomet powered by two GE J-31 jet engines.
Read first hand accounts. Like the genocidal powers that succeeded the Nazis, the Nazis blackmailed the scientists. Threatening to kill entire families if they failed. North Korea style pressure. But that’s why these scientists preferred to flee west to the US than to the Soviet Union. Under the Soviet Union they’d be under the same treatment.
Lead by a certain Austrian man.
