If Eric "Winkle" Brown says "It's a killer!" they should've literally gone back to the drawing board and started all over again! That guy had so much experience in so many aircraft. Including the Me 163 Komet, so he'd flown fast, tailless, swept wing aircraft before & was probably the only person, at that time, who had the experience to opine about the Swallow. I wouldn't've touched it with a bargepole if I'd heard what Captain "Winkle" Brown had said about the Swallow!
@@bigblue6917 Yup, they lost the bloke that could've helped them most because nobody wanted to work with a German. Typical English racism. I HATE IT! It's why brexit happened. Disgusting!
On a slightly related note, if you have an interest in De Havilland, I would really recommend visiting the De Havilland museum at London Colney, Hertfordshire, containing the first prototype of the Mosquito. It doesn't get the recognition of Duxford or Hendon but it's been maintained with care by volunteers and really deserves more attention.
That place will always be a favourite with me. In April 1989 my dad and I flew from Canada to the UK to visit air museums. Very soon after arrival we realized the Mosquito Aircraft Museum (as it was then called) was open only that day out of the days we would be in the country, so from our B&B we called a taxi and went straight to London Colney. We'd been at MAM maybe twenty minutes when the docent, finding out we had come from Canada, had me climb aboard W4050...

One thing you didn't mention about Geoffrey De Havilland Jr.'s crash of the DH 108 was that, after the crash, he was found to have a broken neck/spine. It is thought that the violent oscillations that the swallow was experiencing caused the quite-tall De Havilland Jr to hit his head hard on the canopy and break his neck/spine. I read about this in "Wings on my sleeve" by Eric Brown, and I would highly recommend that book to those who haven't read it and like aviation.
I heard Eric Brown tell this very story during an interview available on the RAeS Podcast. He said that he had sought information from the engineers in charge of wind tunnel testing. He was to a certain extent aware of the possibility of violent pitch oscillations and he had therefore placed his seat as far low as possible prior to duplicating G. De Havilland's accident flight profile. This, with his smaller height, prevented his head from violently hitting the canopy when the oscillations suddenly began - which as you said had killed G. De Havilland. He then eased the throttle back and gently pulled back on the stick and the phenomenon ceased as suddenly as it had begun. He discribed the oscillations as much more extreme that wind tunnel investigations had anticipated.
If the late Captain Eric "winkle" Brown was critical of an aircrafts handling and saftey then you BETTER sit up and take notice....that man KNEW EXACTLY what he was talking about.
A very revealing clue to the cause of the _Swallow Disaster_ the antiquated de Havilland company was attempting to build supersonic jets at a time when it was still building its aircraft primarily from WOOD...
I would love to see a video on an important American aircraft I have not seen a video on. That being the Beechcraft 18. This aircraft was in production from 1937 to 1970. Which is something of a record in itself. I was responsible for training the cast majority of the navigators and the bombardiers for the USACC. Some of these aircraft still fly today.
12:30 - that Model A (?) in the background ... it's always fascinating to see an at the time modern machine, a plane, train, etc., parked right besides the time anchor like that..
@@Dave5843-d9m It was only half-finished at best, so it couldn't have been just before it was due to fly. To be fair, my father has my book and I've never actually got to read it.
The particularly remarkable kind of courage possessed by that generation of test flyers through the supersonic R&D era cannot be overstated. These were extraordinary men who understood the demands, rewards and consequences like few other human beings in history have ever realized. They all well knew they were risking there lives proving radically new designs while pushing the envelope of knowledge for the advancement of aviation. These were incredible individuals to be remembered - not for how they died, but how they bravely lived life so close to the edge!
A truly shameful chapter in British history as the U.K. desparately fought to remain relevant in the postwar aircraft industry... By the end of the war Britain was not only broke it was years behind in aircraft technology, de Havilland especially was decades behind and began making extremely risky gamble with new designs that were way beyond the technical experience the company had.. This game of bad management and reckless engineering would ultimately culminate in the worst engineering failure in commercial jet aircraft history... the _Comet Disaster_ Bad designs like the Swallow, Vampire, Comet and Sea Vixen would eventually bring the inevitable demise of the once great British aircraft company and signal the start downward spiral of the entire UK aircraft industry into complete collapse. The current RAF fleet consists of almost entirely foreign designed or built aircraft... its most advanced jet fighter being the American Lockheed F-35.
@ShiftingDrifter - Yes. And we might have pointed to the rapid pace of testing, and said "they should have been more cautious", but at least some of the exciting new problems they encountered weren't linear in nature - you could speed up, or move the controls, and a problem would appear that didn't start small and get worse - a huge problem would suddenly reveal itself in a way that gave no warning. Having a plane in a shallow dive suddenly break an experienced test pilot's neck is a good example.
I'm currently reading "Jet Jockeys" (Caygill, 2002), which covers the introduction of several jet types to the RAF to the end of the 1950s. There were a few death traps.
Some time ago I came across some figures about the deaths of trainee test pilots in the US in the 50s. Half of all trainees died during training. This did make me wonder of those who survived the course how many passed.
I you haven't already, you should read "Wings on my Sleeve", the Biography of Eric "Winkle" Brown. He flew hundreds (no typo) different Aircraft types, is the pilot with the most carrier landings (2407!) and flew all German jet fighters. The man taught himself how to fly helicopters by reading the manual.
@@malcontender6319 50% survival rate in combat is horrendous.... But in training??? The word horrendous is inadequate. I just can't think of anything else.
Initial design work started before the end of the war and access to Me. 163 was possible. The UK did have its own research in this area, though, such as en.wikipedia.org/wiki/Handley_Page_Manx.
I think the big problem was that the DH. 108 was essentially a flying wing with single vertical tail. It's too bad de Havilland couldn't get access to the Horten brothers, who probably would have told de Havilland to design the wing with more control surfaces to better control the pitch, yaw and roll of the plane. (After all, the Horten brothers did manage to build and fly an all-flying wing jet fighter prototype with two Junkers Jumo 004 turbojets that actually flew quite well.)
@@rob5944 Yes they were. Unfortunately they, or the manufacturers got lost in a sea of details. Their weapons were often too complicated and required constant maintenance. That was especially true of their tanks. Early jet engines, all of them, had lifetimes measured in hours.
Do modern aircraft design engineers ever train their graduate staff by presenting them with historic aircraft designs and giving them the task of using computer simulation to evaluate how each aircraft would behave and see how accurate their analysis is? And then give them the task of suggesting improvements? It would be fascinating to know what the latest Boeing or Airbus simulator technology would make of these early designs.
de Havilland aircraft are often taught in engineering classrooms as examples of what can go wrong in the design and manufacturing process, the d-h Comet is another aircraft frequently discussed .
It's a great looking plane and clips early in the vid make it look like it had great handling, pity it was a tad lethal. If Eric Brown says its a pig, you know it's fact
I saw one of these, or something close, sitting in the weeds behind a hangar in Arizona. It was in a sad state and I was startled to see plywood in it's construction.
Wing fences. They keep the air from going along the wingspan, instead of just going directly over the wing chord. Look at the MiG-15 and 17 for another example
On the third crash, it was thought the pilot lost conciousness due to lack of oxygen. But radio reception of him screaming all the way down eliminated that posibility!
Another great video Rex! Beautiful looking aircraft but I always thought it had too much wing area, considering it no longer carried the weight of the Vampire tail booms and empennage. If a foot or more had been lopped off each wingtip it may have been under less wing stress that lead to the crashes. But that's just my armchair conjecture.
Don't forget Swallow's 1a, & 2a, ha ha. I love the way you put things into a concise manner. To heck with repeat formalities, excellent video's by the way. I see on the same page here, a thumbnail of Jet Flying Boats by another reliable source of aviation history. Take care adios
I have not seen it for about 30 years but there is a British movie about this that came out in the '50s . The movie is called " The Sound Barrier " . The film covers most of the issues covered in this video , but of course is 1950's melodramatic . It maybe on UA-cam somewhere . If you have time , maybe worth a look .
If it was made with a Vampire nose (which was made of wood), it may have been the only (?) aircraft with major wood construction to go supersonic (or transonic)
De Havilland copied the design from the Me 163, this being the fastest WW2 aircraft. But unfortunately also copied its flawed flying characteristics. The Me 163 had a speed limit of 1000 kph due to instability as it approached the speed of sound, the Germans were only too aware of this due to numerous testing accidents . The Swallow with more sophisticated aerodynamics was able to pass this barrier, but still ultimately only by a small margin before succumbing itself. This was the only de Havilland design that was not originally conceived in-house, and the test pilots paid the price. There are no short cuts in aviation.
During his career as a test pilot Geoffrey de Havilland wore the standard leather flying helmet. After his death some US test pilots, having heard about his death and its cause, sent some of the newer 'done dome' type helmets which US pilots had started to use in order to avoid any more such loses. Alexander Lippisch, the man behind the Me 163 had been in Britain but by the time they came to design the Swallow he was in America.
Its shape reminds me of a foam glider I had when I was a kid. It was a yellowish color with a hook moulded into the belly, for launching by a rubber band on a stick. That would have been around 1975 or so.
Other sources say that the crash of swallow 2 was the result of violent pitch oscillations that broke Geoffrey deHavilland's neck. Eric Brown in swallow 3 also experienced these oscillations but survived because he was shorter
Interesting that they actually lengthened the Vampire fuselage, as the reason for its stubbiness in the first place was to keep the jet pipe as short as possible.
Hindsight being 20/20 we can see why: as it pokes tgrough the sound barrier the leading edge of the wings will lose lift, the trailing edges then attempting to flip the plane a la MiG 19.
@@nickdanger3802 Without really wishing to get into a discussion with someone who is so obviously anti British technology , the Rolls Royce Nene had a thrust rating of 5000 lbs ( The first in the world )
Welcome back from your Holiday. This another aircraft I knew absolutely nothing about. Thank you, it's kinda like in the Matrix...I know karate..... I know the Swallow..
Chuck Yeager in his autobiobraphy claims the X-1 did go supersonic in that flight. The point was to beat the Douglas Skyrocket, which in its initial version had both a jet and a rocket engine and took off from the ground.
Incidentally, you need new intro sounds, now we've reached the jet age! Perhaps the sound of one of the earliest jet engines? (Something a bit more interesting than the jets we're all used to these days - if such exists.)
@@blackroberts6290 Yes .... but that wasn't what I asked ! Bell X-1 had a *rocket* engine - not a *jet* engine - the two are very different ! I was wondering which aeroplane with a *jet* engine was the first to break Mach 1.
@@MothaLuva That's like the "guns don't kill, bullets do" joke. Yea, the problem was stress fractures around the rivets, but the square windows helped concentrate the stress and were the part that failed under stress. That definitely makes them part of the problem.
I don’t think there’s any way this aircraft could have passed thru transonic speeds without a powered trimmable tail plane. That’s why it broke up in flight.
Rex, please compare and contrast the De Havilland Swallow with the Messerschmitt Me-163 Komet. The aircraft were roughly contemporary and it seems the Swallow was inspired by the Komet. Why was the Komet aerodynamically successful, except for that T-Stoff/C-Stoff hypergolic thing, where the Swallow was not? This is puzzling as the British had, by this time, the German technical data from the Komet program.
Komet had a wing that was too thick for supersonic flight, partially owing to its wooden construction, and partially to having to contain flaps and spoilers to make up for the loss of the tailplane. Eric Brown flew the Komet and raved abut its handling.
The Germans had little data on compressibility, or wind tunnel experience past mach 1. The 163 would exhibit control reversal at around .9 mach. The excessive wing sweep of 60 degrees, compared to the 23.5 degrees on the 163, might have caused issues with spanwise flow, with the aerodynamic center moving aft as speed increased. Eary MIGS all had wing fences to help control it. It was probably a poor choice for high-speed flight test, the shock wave causing the elevons to lock up and become ineffective. The advantages of the all flying stabilator, as on the F-86 Sabre jet were not (made) available (to the British) or known of at the time.
If Brown could fly it and come back and say it was a killer then maybe you could use a fbw system to restrict the flight envelope to a known safe area. But you'd probably kill even more test pilots finding out the safe limits and you'd end up with a severely restricted flying machine. That's no fun. And not 'successful' when put next to more well- behaved aircraft.
Wasn't the F-86 Sabre the first airplane to break the sound barrier which took off under it's own power? I remember reading, that it broke the sound barrier not long after the X-1 did.
Mach tuck. Not to be confused with MacTac, which is sticky tape printed to resemble wood veneer. (And which probably wouldn't have been much help holding the DH108 together anyway...) 🙄
I remember Geoffrey de Havilland being killed - I was quite cut-up about it. But for years and years I wrongly believed that he was flying a prototype of DH110.

The film covers most of the issues covered in this video , but of course is 1950's melodramatic . It maybe on UA-cam somewhere . If you have time , maybe worth a look .
Good film. I have the DVD but sadly it does not feature this aircraft. The ‘hero’ aircraft in the film is a Supermarine Swift.
Nice plan-form, almost Horton-like.
What was this frenzy of activity with the British Aerospace industry. Was the nation not still under rationing and lendlease?
Good point, Britain would not have the resources or technology to build a supersonic aircraft until 1954.
@WilhelmKarsten what became of this Aeroplane?
@@JeffreyWilliams-dr7qe It was canceled.
Britain only made one supersonic aircraft, the English Electric Lightning.
@WilhelmKarsten Did not know about this disaster craft until UA-cam.
@@JeffreyWilliams-dr7qe de Havilland made a lot of disaster aircraft... which is why the company failed in 1958.
As someone who used to fly RC combat wings, NEVER stall a flying wing.
I've gotta try that in KSP.
No issue if stalling a Fauvel flying wing
Please, tell us why.

My flying-wing always comes back to me when I throw it.
@@jefffefferson8339 Remember in Top Gun how Gooses’ plane went into a flat spin and crashed? Same idea
If it was made with a Vampire nose (which was made of wood), it may have been the only (?) aircraft with major wood construction to go supersonic (or transonic)
If a faster-than-sound wooden plane falls in a forest, does it make a sound?
@@AllonKirtchik One wood expect it wood, but it's not a very sound theory 🥸
It looks so much like the German Comet although with larger wings.
De Havilland copied the design from the Me 163, this being the fastest WW2 aircraft. But unfortunately also copied its flawed flying characteristics. The Me 163 had a speed limit of 1000 kph due to instability as it approached the speed of sound, the Germans were only too aware of this due to numerous testing accidents . The Swallow with more sophisticated aerodynamics was able to pass this barrier, but still ultimately only by a small margin before succumbing itself.
This was the only de Havilland design that was not originally conceived in-house, and the test pilots paid the price. There are no short cuts in aviation.
Hey, just because it was an exact copy doesn't mean it was an exact copy. They changed the K to a C
@@chrisknight6884 I think you need to do some due diligence and properly research...
It's interesting that they called it "Swallow" when the ME-262 was called "Schwalbe" which also means Swallow...
Great video 👍👍
Thank you
During his career as a test pilot Geoffrey de Havilland wore the standard leather flying helmet. After his death some US test pilots, having heard about his death and its cause, sent some of the newer 'done dome' type helmets which US pilots had started to use in order to avoid any more such loses. Alexander Lippisch, the man behind the Me 163 had been in Britain but by the time they came to design the Swallow he was in America.
Of course, no helmet in the world will save a pilot when their plane violently disintegrates mid-air, like de Havilland Jr's plane did.
YAY! Finally Thé Swallow(deep) :-O
Thanks Rex' ♥
Its shape reminds me of a foam glider I had when I was a kid. It was a yellowish color with a hook moulded into the belly, for launching by a rubber band on a stick. That would have been around 1975 or so.
With a similar tendency to crash land...
You should do a number on the wartime German tailless aircraft by Alexander Lippisch and the Horten Brothers, Rex.
Can you do a video on the Avro Canada Aerocar
The De Haviland Vampire and the English Electric Lightning are my favourite British jet fighters.
Other sources say that the crash of swallow 2 was the result of violent pitch oscillations that broke Geoffrey deHavilland's neck. Eric Brown in swallow 3 also experienced these oscillations but survived because he was shorter
Although I know it's been pretty well covered I really hope you do a video on the Avro Arrow
Interesting that they actually lengthened the Vampire fuselage, as the reason for its stubbiness in the first place was to keep the jet pipe as short as possible.
That thing looks like a jet engined version of the Me 163.
The Sound barrier can't be that hard!
*The Sound Barrier was very hard*
"How hard could it be?" - Jeremy Clarkson.
Any relation to the Komet Me163?
looks to me that they made a copy of a german me163 comet and put a jet in it
Cool thanks
Although, of course, those square cabin windows have since been exonerated. The fuselage failure started in the roof, around a radio aerial panel.
Apparently the holes for the rivets were punched rather than drilled leading to weakness.
Always interesting, Rex. :>)
Hindsight being 20/20 we can see why: as it pokes tgrough the sound barrier the leading edge of the wings will lose lift, the trailing edges then attempting to flip the plane a la MiG 19.
The DH-108 wasn't supersonic... they crashed like many de Havilland aircraft did, due to poor design and shoddy workmanship.
Although inofficial, the first AC to break the sound barrier was the Me-163A.
Makes me wonder if the Me 163 could have been adapted to use a jet engine?
Maybe the addition of a tail may have solved the handling issues?
Am I wrong in thinking this aircraft has a similar appearance to the German ME-163 rocket fighter of World War Two?
Similar, since both had no tails, but not as close as you might imagine.
Needed rear stabilators ( all moving tail ) and a more powerful engine ..like the Miles M 52
Which engine?
@@nickdanger3802 Without really wishing to get into a discussion with someone who is so obviously anti British technology , the Rolls Royce Nene had a thrust rating of 5000 lbs ( The first in the world )
From the Bell X-3 school of "make it look cool and I'm sure it'll work fine"
Welcome back from your Holiday.
This another aircraft I knew absolutely nothing about.
Thank you, it's kinda like in the Matrix...I know karate..... I know the Swallow..
The Bell X-1 actually did one take off from the ground though it did not go supersonic on that flight.
It was a 'jab' at Douglas, not De Havilland.
Chuck Yeager in his autobiobraphy claims the X-1 did go supersonic in that flight. The point was to beat the Douglas Skyrocket, which in its initial version had both a jet and a rocket engine and took off from the ground.
I give the English credit for having the first supersonic flight with a usable power plant that still works to this day
The English did not have the first supersonic aircraft..
They would not have a supersonic jet until 1954.
Incidentally, you need new intro sounds, now we've reached the jet age! Perhaps the sound of one of the earliest jet engines? (Something a bit more interesting than the jets we're all used to these days - if such exists.)
Was the Swallow the first *jet* to go supersonic as opposed t thr Bell *rocket* powered aircraft ?
I suppose I could always Google it .....
the video title says: Swallow was the first for Britain.
Also Bell wasn't really a plane, it was air launched crewed rocket, again its explained in video.
@@blackroberts6290 Yes .... but that wasn't what I asked !
Bell X-1 had a *rocket* engine - not a *jet* engine - the two are very different !
I was wondering which aeroplane with a *jet* engine was the first to break Mach 1.
Two minutes in sees design that will become the Comet. Sees square windows. Shakes head sadly.
Indeed. Not a good idea.
ua-cam.com/video/2rvx-r2itrE/v-deo.html
The square windows were not the problem…
@@MothaLuva That's like the "guns don't kill, bullets do" joke. Yea, the problem was stress fractures around the rivets, but the square windows helped concentrate the stress and were the part that failed under stress. That definitely makes them part of the problem.
Yet you can maybe see the wing-plan in the Vixen.(DH110)
Yes, the Vixen also had a propensity to crash killing the pilot.
Looks like someone at De Haviland looked at the Me-163 and thought "Hey, I can do that".
I don’t think there’s any way this aircraft could have passed thru transonic speeds without a powered trimmable tail plane. That’s why it broke up in flight.
Rex, please compare and contrast the De Havilland Swallow with the Messerschmitt Me-163 Komet. The aircraft were roughly contemporary and it seems the Swallow was inspired by the Komet. Why was the Komet aerodynamically successful, except for that T-Stoff/C-Stoff hypergolic thing, where the Swallow was not? This is puzzling as the British had, by this time, the German technical data from the Komet program.
Komet had a wing that was too thick for supersonic flight, partially owing to its wooden construction, and partially to having to contain flaps and spoilers to make up for the loss of the tailplane.
Eric Brown flew the Komet and raved abut its handling.
The Germans had little data on compressibility, or wind tunnel experience past mach 1. The 163 would exhibit control reversal at around .9 mach. The excessive wing sweep of 60 degrees, compared to the 23.5 degrees on the 163, might have caused issues with spanwise flow, with the aerodynamic center moving aft as speed increased. Eary MIGS all had wing fences to help control it. It was probably a poor choice for high-speed flight test, the shock wave causing the elevons to lock up and become ineffective. The advantages of the all flying stabilator, as on the F-86 Sabre jet were not (made) available (to the British) or known of at the time.
Reminds me slightly of the Me-163 rocket olane
Do you think the swallow could have been more successful if it were a more modern fly-by-wire system?
If Brown could fly it and come back and say it was a killer then maybe you could use a fbw system to restrict the flight envelope to a known safe area. But you'd probably kill even more test pilots finding out the safe limits and you'd end up with a severely restricted flying machine. That's no fun. And not 'successful' when put next to more well- behaved aircraft.
The Bell X1 used a fly-by-wire Stabilator trim control copied from the Messerschmitt Me-262.
Sorry babe, gonna have to cancel our plans, Rex's Hangar posted
Wasn't the F-86 Sabre the first airplane to break the sound barrier which took off under it's own power? I remember reading, that it broke the sound barrier not long after the X-1 did.
Some claim it actually flew supersonic the day before the X-1. See Dan Hampton's "Chasing the Demon."
@@johnshepherd8687 Yes, that rings a bell.
Mach tuck.
Not to be confused with MacTac, which is sticky tape printed to resemble wood veneer. (And which probably wouldn't have been much help holding the DH108 together anyway...) 🙄
it looks amazing ! very much in the steps of the Me 162 Komet
Rex KEEP THE PROPELLOR intro! It is your own meme!
Mach 1 stayed together?
No, disintegrated before reaching Mach 1
I remember Geoffrey de Havilland being killed - I was quite cut-up about it. But for years and years I wrongly believed that he was flying a prototype of DH110.
As an aside, Vampire is a cool name for a plane.
It amazes me how small it was.
Why was it experience it's critical Mach Number at 350 mph? That isn't even half way to Mach 1.
Yes, that would indicate a poor aerodynamic design
No doubt heavily inspired by the ME 163...
The Brabazon Committee was disastrous!
As every time politicians interfered in developing aircrafts.
Looks like a copy of the Me 163
