Quite a few people have commented on the topic of the round windows. Check out the 'Square window myths' paragraph on Wikipedia :) en.wikipedia.org/wiki/De_Havilland_Comet
Well that was an interesting read, so much for my earlier post. It was a well spread myth even Air Crash Investigation got it wrong, we are never too old to learn!
If circumstances had not been so cruel to the British then the De-Havilland Comet 2s would get Avon which would have allowed the Comet 3 and 4 to take the 15,000ibf Rolls-Royce RB.106 engine
the FAA according to their website will dispute its not a myth - the windows were a factor
@@speedbird737Have you actually seen any pictures of the De-Havilland Comet 1?
They had rounded square windows and it was the way they were installed that was the problem and not the design of the windows because the De-Havilland Comet 1 was actually a very sound design but no one understood about metal fatigue and do not even try to bring up the BS of "De-Havilland did not know about pressurisation"
De-Havilland did know about pressurisation but we should remember that no one had built a jet airliner before the De-Havilland Comet
@@Knight6831 correct so in conclusion the windows were an issue (regardless of if a good design or not) even the BAE website said :"It identified that despite extensive testing in the design stage, the cyclical pressurisation and subsequent depressurisation of the fuselage had accelerated the stress levels. This had caused cracks and fissures around the corners of the ADF, and some the main passenger windows, causing disastrous fractures in the structure and an almost instant failure of the airframe."
Whats amazing is the design of this airplane looks more futuristic than current model airplanes.
It looks very 40s. The integrated engines, the square windows. The big landing gear
@@MrJimheerenthe comet 4 has circle windows. Perhaps if it had modern oval windows it would change your perspective
@@ScotlandTheBrave_1 I was thinking about the Comet 1. But yeah the 4 definitely looks quite futuristic and old fashioned at the same time
Reminds me of the young Americans in the 1st Gulf War……. Victors arriving, them thinking it was some new super secret Limey wonder weapon……
……..again, a sort of Flash Gordon steam punk vibe 🥳
Nothing about this aircraft says "future" maybe in the context of the time it was designed, sure but now, no it doesn't. You're conflating "Futuristic" with "Different".
I flew twice as a passenger on this aircraft, 30.09.1962 flown from Culcutta to Singapore, 6.12.64 flown from Culcutta to London,. I know this thanks to something called the "Junior Jet Cub" who provided me with a log book and its all recorded in there. A great aircraft!
It is kind of sad seeing that aircraft land locked forever. The places it's been, the memories made by it. A shell of its former self
What was the experience like
@@Rich72James I was very young at the time but I do remember flying in the aircraft and being shown the cockpit. To my small eyes it was very spacious and comfortable, ofcourse the reality was that it was quite "snug" up front! According to my log book I also flew in G-APDH as well as G-APDB. I believe DH was written off after a heavy landing broke the undercarrage in Singapore.
Are you aware this class of plane had a fatal design flaw that resulted in crashes and hundreds of fatalities?
@@glieseseventen4921 they fixed that. I'm sure it did not help it's credibility. That is probably why the 707 was much more successful
The Comet’s nose, fuselage, and wings look so sleek and modern, yet the tail section looks like it was borrowed from a ‘40s propeller aircraft. Great video.
Actually the Comet has a very distinctive 1920s Art Deco style that was very dated looking for the 1950s...
The nose is copied from the Boeing 307 which was introduced in 1937.
I was a passenger in a BEA Comet 4B in early 1960’s. Rome-Paris-London. Your shot of the flight deck was of interest to me especially the nose wheel steering. When leaving Paris the aeroplane started to accelerate on the taxiway, rounding a curve picking up speed, entered the runway, continued to accelerate and took off in one continuous movement. I can now visualise the captain sitting there with one hand on the ‘steering wheel’ and the other on the throttles. The aeroplane was lightly loaded, very few passengers and probably not much fuel. I don’t know what angle we were at initial climb but it was steep. We were pressed back in our seats and a fellow passenger on the adjacent aisle had a bag suspended on the seat in front of him. I recall looking at the angle this freely suspended bag was making and thinking Wow
During the early 60s my late father was Chief Instructor with East African Airways. As a teenager I had the pleasure of flying in each of the airline’s three Comet 4s including on the flight deck across the Sahara and for a landing at Heathrow where we taxied slowly so the crew could watch a VC10 takeoff. The Comet 4 was a beautiful aeroplane in its day. Many thanks for rekindling memories and for a very well-balanced video.
Wow that’s incredible thanks for sharing
Wow. I flew a few times with East African but on VC10s. My father was however in the drawing office of de Havilland from the war on (with a break till 1957) and worked on the Comet.
@@stevenr2463 amazing how these videos can bring people with similar experiences like this together
Excellent...what lovely memories. I lived in Zanzibar in the early 50s and 60s and remember all the Royal Mail DC 3 aircraft of the time. There was the odd DH89a and then F27 Friendship turboprop came later. I purchased a book about the history of East African Airways. 🙌.
@@stevenr2463 🙏👍👍👍👍🙏🙏
I’m an airline captain. I have been flying since age three way back in the 1960’s. I have lived aircraft all my life. I’ve been blessed to fly a lot of aircraft and can identify 90% of all aircraft at quite a distance.
The comet was a beautiful aircraft. It’s just a shame there were pressurization fatigue issues early on. I still think the 707 would ultimately have won out but the comet, had it been successful, would have lead to an updated jet that most certainly would have give boing a run for its money.
It was so beautiful and looked incredibly ahead of it’s time people must have been in awe of this back in the 50s
if we are in awe in 2023, surely they were in even more awe 70 years ago!
its*
Oh my goodness! This is nostalgia on steroids. I flew on the Comet 4c from 1960 to 1966 from Malaya to England and back every year, and first class too (it's a long story).
It is such a gorgeous looking aircraft, and I recall many hours gazing out of the windows at the clouds below where it was always sunny in daytime. But the real treat of a flight would be invited to go into the cockpit and sit in the Captain's seat. Awesome. Your walk through the inside brought tingles to my spine. It did indeed seem to be the golden age of air travel.
I still have my BOAC Junior Jet Club Certificate and Log Book.
This plane must have been a true heartbreaker for Britain's aerospace industry.
You've simply got to love that retro futurism of the age
Very interesting. Being a young plane spotter in the late 70s, I only ever saw a Comet in operation once, as we generally went to Heathrow, where no Comets were operating at that time. But one Sunday afternoon in 1978, we made a brief stop at Gatwick on the way home to London from Brighton. We got there just in time to see a Dan Air Comet take to the air, it was quite a sight!
I remember Dan Air comets at Gatwick, way back in the day, seen when disembarking from British Caledonian VC10 and 707s.
Flew to Corfu in 1980 with Dan Air on a Comet.
I flew to Portugal from Gatwick 1979 dan air , felt lucky to fly in it , must have been coming to the end of its service , nice smooth flight
It’s tragic downfall failures were definitely, well, sad. However could you imagine stepping out of a DC3 and into flying in the comet, I would be like flying to Texas in a 737 or a320 and flying home on starship l. The difference in technology for the day was outstanding. Regardless of it’s inevitable downfall she was the queen of the skies in her time. Nice little video Paul 👌🏻
What a beautiful aircraft.
My father flew this exact aircraft many times as navigator. From his logs, the first entry for G-APDB is 19 September 1959 London-Gander (6h35m) and the final one is 19 December 1960 Sailsbury-Nairobi-Khartoum (3h00m+3h05m). Shortly after, he switched to Boeing 707s as pilot.
Dream job, I am sure he had many exciting tales to tell you.
@@stevetaylor8698 Since many neighbours were also flight crew, this was normal, daily life for us as children. It was just a job, like a bus driver, or a train driver. What I noticed as I grew up was that they all seemed to be exceptionally clever, capable people, apparently able to do anything and everything.
@@cdl0 👍👍👍👍👍
@@mal_752 Thanks: you deserve a story from days of yore. As often happened, when we were taken to a museum, such as Duxford, the adults would be reminiscing about the exhibits they has flown, while the children would be laughing their heads off about the fact that that their parents were so old that they had flown these ancient, obsolete machines. That is the way it was. 🙂
He must have flown with my late father Jim Manning, a captain at that time.
Hello, my grandfather was one of the first Captains of DH Comets of Aerolíneas Argentinas in the sixties. Then he flew Boeing 707 till 1975 when he retired with 22000hs of flight.
Great job with your Chanel, sorry about my english...
Greetings from Buenos Aires Argentina 🇦🇷
Until now I had not realised how beautiful the Comet is.
I am 70 years old and being from central U.S.I have little memory of the Comet especially the early designs. It is a tremendous history I appreciate reference to the early body warping and the beautiful shots of the cockpit. Thanks for another great presentation!
Thank you, sir, for commenting on anything your many years of experience may have seen so it can be recorded forever here on CZcams for prosperity's sake and for the benefit of those younger and less experienced than yourself. Any comment you make can only improve the younger generation's knowledge. Best wishes from Australia.
@@DropBear69 In Washington DC I knew a British Colonial Administrator who grew up in England during WWII and was assigned to Malaysia. He commented that he flew on the Comet and loved the appearance of the design. He was very proud of it. In the 1960s I attended an Strategic Air Command airshow and the flight crew of a Nimrod took my aboard for a tour. Maybe more likely a Hadley Page Victor Bomber. I would of been eleven years old and the British Officers were extremely good to me. I regret I was likely deplorable child. In closing in the 1980s I flew in a 1950s Lockheed Electra turboprop passenger plan. That class of plane at its introduction experienced engines ripping themselves off the wings with I believe the total loss of the planes. I was amazed at just how heavily the fuselage was constructed it felt like a flying tank. The designers were very conservative and regardless had engines flying off the wings. This Lockheed was used by the United States military for a similar purpose as the Nimrod.
@@josephpiskac2781 Nimmy's, eh? I worked on an RAF base (now Army) as a civvy worker in one of the Messes that operated Nimrod MR2's. So, very much a regular sight in my area. The house I live at was under one of their landing circuit paths and there was rarely a quite moment, when those old Rolls Royce Spey engines got close. I was in the local ATC back in the Nineties, and went on few Air Experience Flights in them. Very sad day when they stopped operating.
Nowadays, our local aviation museum has a forward fuselage/nose section that's open for the public to walk through and a whole Nimrod on the camp, that sits engineless on a dispersal area near the coast, after the MoD had it kicked out of its hanger.
Seeing a De-Havilland Comet at Melbournes then International airport at Essendin in the early 1960’s as a young boy made a big impression with me still to this day and obviously was one of the few Jetliners that could land there as Melburnians had to go to Sydney mostly to travel overseas on a 707 or DC-8 as they were not able to use Essendon until Tullamarine opened in the 1970’s, thanks for the great tour to my mind the most aesthetic jetliner that has ever been built! 👌
My old man flew the Comet 4 and Super VC10 for East African Airways. He loved the Comet
Great video Paul! I remember your previous tour around this aircraft at duxford so it's good to see it again in 4K and much longer with more information!
This is fantastic. I flew Comet 4C DanAir Manchester to Athens around Aug 1977 I think. I was 11 at the time and remember being sat by the large window. Just a beautiful aircraft in my humble opinion. I've been interested in civil aircraft ever since. Thanks for this well presented video.
I also flew Dan Air Comet about the same time and same age!
Such a beautiful plane. I love the look of the integrated engines.
I flew in a Comet from London to Berlin (I think) I was only about 5 years old and can barely remember it, but can recall walking across the tarmac to the plane, on a cold, windy, rainy day.
Took me up to 30sec before i realized that this wasnt a new plane xD. Love the design!
Thank you stating the facts. A lot of people complain about the coach class seating nowadays and compare it with the flying quality 50 years ago, without considering the fact for the price they have to pay for a coach class today vs flying back in the "good old days"...
Good video Paul.
I agree
My parents flew to their honeymoon in London on a BOAC Comet 4. And luckily, they also took a photo of it!
Excellent video.
I was lucky enough to fly on the Comet 4 twice with MSA in December of 1967 and again a year later, from Singapore to Hong Kong.
Both flights were memorable as each time I had a window seat on right side for the Kowloon approach to Kai Tak.
I really enjoy your tours round British aircraft and museums. I've always loved Duxford and cosford museums two of our best ones. The smaller museums are really interesting too.
There was a cockpit from a Comet on display at Gatwick for a while back in the 90's. I remember being amazed at how cramped and complicated it looked compared to modern aircraft.
The Commet ❤ it . Really appreciate the 4 engines built in2 the Wings
Been in and worked on this very Comet at Duxford.Fascinating.ln immaculate condition and well looked after,and a thorough insight in to the "Golden Years" of airliner operations👍
Thanks Paul for the great tour of this wonderful aircraft.
The Comet might be, to me, the most beautiful jet ever designed. Brilliantly sleek!
Great video Paul! Your videos keep getting better and better and I always learn something new about the iconic aircraft you feature. Well done to the IWM Museum for preserving this classic and letting you film this video for us all on the internet!
Thank you for sharing this. I really enjoyed this tour on the DeHavilland Commet. The whole story of how this aircraft came into existence as well as it going in connection with the leap into the jet age is beautiful and amazing.
Beautiful. Now almost every airliner has engined hanging from the wings. Maintenance is obviously easier, but the lines of the Comet with it’s inboard engines was a true design classic.
If the engine would catch fire or explode it could out take out the wing. that is the reason they moved away from this design.
Paul thanks for this wonderful video about Comet
Very welcome
Another fantastic tour! Can't wait to see this one myself in a few months 😍
Cheers and enjoy! Duxford is brilliant! Might need two days, though. :)
Great video. I loved this aircraft having flown them many times.❤
Best videos I have seen on this channel yet
Glad to hear. Why do you think it’s the best? I’m always keen to hear co constructive feedback! :)
Always liked this plane. Smooth body no protruding engines under the wing just looks so slick. I amagine working on engins was a bear, though. Thanks for the show.
I flew on a Comet IV of United Arab Airlines in 1964. (The Year of Living Dangerously!) My preferred aircraft in those days was the VC10.
Now my favourite is the A380.
My very first airliner flight was in a Comet 4B, LHR to the long defunct Oslo Fornebu in about 1963. Had me hooked on everything airplane related ever since...!
Ah love this plane. This one used to be sitting on the tarmac at Hatfield Aerodrome long after they shut down. Every weekend as a kid we'd drive past it on the way to go shopping.
Takes me back!
I had my first ever flight deck visit on a Dan Air Comet IV when I was 7 years old, on our way to the Canaries. Passing the Pyrenees, the skipper had his feet up, reading a newspaper.
He turned round, peering over the top of his half-moons, and said 'Don't touch anything!'
I thought this was super cool, and it ignited my passion for aviation (that, and growing up, near Binbrook)!
Some 50+ years later, and I'm now a skipper of the 787 with a rather well known British outfit. Nowhere near as cool as the Comet though!
Thank you so much for making these videos and documenting/sharind these dying marvels of engineering! ❤️
Love the contours on this aircraft. The enclosed engines look Cool. I've never seen one of these before.Nice looking Bird.
First time I saw a vid in this channel! Love it! What a mountain of info! Keep it up
Another great plane I often flew back and forth from the UK to Cyprus in the 1960’s…very comfortable…I still recall the rather old fashioned cockpit…even back then , to my eyes…..lovely to fly in, seeing the Alps for the first time, looking out the large windows…..oh those were the days….lucky 5 year old….
Was hoping you would do a video on the Comet. I looked and looked the other day. Thank you for your work.
I love the sextants in the cockpit. I love old school tech. Fab plane, superb museum. Love all your videos.
An absolute work of art!!!!!
Paul, thank you for such an informative tour of the Comet 4. Although I don't remember our destination-perhaps London to Barcelona or London to Athens-I flew on a Comet in 1965 when my parents and I lived in the North of England. What a delight to see the Comet again.
Another fascinating tour paul👌
That was an incredible tour. What a great piece of History. Thank you.
Glad you enjoyed it
Thankyou so VERY MUCH for this video. The Comet is my favourite aircraft of all time irrespective of my never traveling on one or the unfortunate accidents that in hindsight benefited the world aviation technology to be safe today. Thankyou so much once again - it's really and truly appreciated
This aircraft is gorgeous.
Thank You Paul.
I grew up in Hatfield around the corner from British Aerospace & DeHavilland Comets always held a special interest for me. I’ve never been to IWM Duxford although done most of the other IWM branches over the years.
Thanks for this. Very informative. Had always wondered why many older, larger aircraft had the twin rudder configuration.
Absolutely beautiful aircraft
I've always considered the Comet to be a very beautiful design, especially with regards to the engines being incorporated into the wings. Not the best idea, but still very pretty. I remember my mother saying she flew on a B.O.A.C. Comet once, and she thought it was a wonderful experience.
Fantastic presentation !
My Uncle worked for De Haviland in the 1950’s at the time this aircraft was developed. Another example of British leading the way, before being overtaken by foreign competitors. He later went on to work for Lockheed in USA, which I suppose was a logical progression of the time. The Comet really was a beautiful aircraft ahead of its time.
A truly shameful and humiliating chapter in British aviation history... de Haviland was decades behind in aircraft technology and its collapse in in 1958 was inevitable
That's so cool! Thanks for sharing!
I have fond memories of flying on a Comet operated by Dan Air in 1972 from Gatwick to Tangiers. The return flight happened to be at the same time as the infamous Staines air crash, although we didn't realise that at the time. That was a BEA Trident aircraft.
Beautiful lines and paint scheme.
Fantastic vid mate, you make really interesting content showing our aviation history like nobody else . Thank you
Been to duxford. Amazing place and well worth a visit.
So glad this showed up on my suggested clips. Earned another subscriber!
Welcome :)
OOOOOOOO!!! A TSR-2 😍😍
That video is coming in a few weeks :)
@@PaulStewartAviation excellent!! Keep up the good work mate 👌👌
Its really sleek and looks awesome
My mother flew from Melbourne to Singapore on BOAC in 1963. The route was Sydney, Darwin,Jakarta & finally Singapore. At the time I remember climbing out of Melbourne it looked like a rocket compared to everything else flying at that time. My mother preferred the Comet to the Boeing 707’s she finished the trip to London on. She made a lot of stops on both the Comet & Qantas Boeing 707.
Fantastic, Paul 🙂
Beautiful! I love this plane and how innovative Comet was. I love how the engines look like. So badass! The interior just felt like a plane from the 80s, not like the first jet engine airliner. (though I have no idea how turbine planes were at that time). thank you so much, this video really made me vibe. I first heard about the Comet a few years ago in a Mustard video, this time a real visit! hope I can go on day to England and visit this museum. Awesome!
What a fantastic and informative video, thank you
note the comet 1 square windows, where these are oval.
the corners are the cracks formed which brought down the 1's. No corners in later models to remove the crack issue
An absolutely beautiful airliner
As a young lad living out in Malaya I recall one of these landing there my dad took some photos of it this was in KL in the late 50,s
The circular windows were also part of the upgrade to distribute the forces on the fuselage more evenly. If I remember correctly, it was the corner of one of the windows that was the occasion for the catastrophic fuselage failure in the earlier model. What a great tour! Thank you.
I think the film told the story it was the windows, but I've read that a hole cut for a radio antenna caused one of the crashes. Basically any stress riser could have been the point of origin, and certainly square corners are stress risers.
@alan mac the square windows were definitely the major cause very early on, after they were redesigned the comet proved to be many times more reliable and safe
Flew in one once to Portugal operated by dan Air 1979 nice smooth flight , felt lucky to fly in it coming to the end of its service
Great video Paul! I do love the DH Comet, there is a museum just off North London dedicated to DeHavilland aircraft and it has the fuselage of a Comet 1, one of only two surviving examples.
Absolutely beautiful 👏👏👏👏👏👏👏👏👏👏👏👏
Wow what a amazing video showing a plane i can never see with a modern camrea. I love this content!
Interesting Paul, after reading John Cunningham's book of test flying and sales, good to actually see the plane, inside and out. I did see this plane at Duxford but no entry on the day.
Thank You.
Its a thing of beauty from any angle
I made my first ever flight in BOAC Comet G-APDE. We left London Heathrow in the bitter winter of early 1963 and flew to to Bombay (now Mumbai) in India, stopping at Frankfurt, Damascus and Abadan. It was indeed noisy sitting next to the engines.
Very nice plane
Beautiful aircraft. You do such a great job on these videos, thank you!
Thanks Mason! More coming
Love your videos. Beautiful narration and presentation.❤
Thank you for this! This is so interesting!👍🏻🇫🇮
Thanks for the video👍
This is an excellent video from an excellent channel. Well filmed, very good job, thanks.
*_Former Boeing Everett...._*
The Comet was way ahead of it's time. The blended engine inlets along leading edges of the wings was both functional and stylish. A no nonsense cockpit laid out to help pilot and first officer focus on what was most important.
*_We owe a lot to the engineers and those who built it._*
But they crashed and FAILED !!!
The Comet Disaster remains the worst engineering failure in commercial aviation and a shameful, humiliating chapter in British history.
The real tragedy of the Comet Disaster is that it could have been easily prevented if de Haviland had simply followed well-known and understood industry standards for the design and construction of pressurized cabins made from riveted aluminum alloys.
The only lesson learned from the Comet was that aircraft manufacturers could no longer be trusted to conduct their own aircraft crash investigations.
Thanks for comment @@WilhelmKarsten
@@SJR_Media_Group It's regrettable that those at de Haviland responsible for the gross incompetence and criminal negligence were never brought to justice although we can all feel safer knowing that de Haviland went out of business in 1958 as a direct result of the _Comet Disaster_ and is no longer killing travellers.
There is nothing more disgraceful and insulting to the memory of the 426 victims than someone attempting to whitewash this horrible scandal and attempt to portray this embarrassing failure as some sort of great technical achievement for Britain... truly shameful.

All Comets, including some Comet 1s, had full civilian use certification at some point after 1954, civilian use certification only being withdrawn after commercial flying stopped. Examples were flying until 1997 - one example did a signals research global circumnavigation flight series in 1993 via Australia virtually without a rest travelling 28000 miles, only had an ice warning indicator issue during the flights.
*The DH Comet - World Firsts.*
1st gas turbine jet powered airliner. 1st high altitude 8psi pressurised full fuselage length passenger cabin airliner, not a trivial feature as structure strength required for pressurisation considerably exceeded strength required for normal flying stress. Nobody else had done anything similar before the Comet.
The b-47 used 2 relatively small, heavily built pressurised modules (the aircraft where 6 had their wings fold up in 2 months while flying & some had their wings fall off while parked).
The 1937 Boeing piston engined airliner pressurised passenger cabin was pressurised to 2 psi only - in fact that could easily be done as the normal unpressurized fuselage cabin structure strength for flying stresses only was all that was needed to be adequate so no significant weight increase issues needed addressing.
1st all hydraulically powered flying surface controls & actuators airliner with under carriage wheel disk brakes + ABS.
1st jet airliner to cross the Atlantic.
1st jet aircraft to do a world circumnavigation flights series.
*Of course De Havilland had prior experience building many all metal construction airframe aircraft including thousands of jet powered fighter aircraft that were primarily of metal construction with pressurised cockpits & jet engines built by De-Havilland & we know the world's first all metal construction airframe airliner was built in England in the 1920s by Handley Page.*
*_De Havilland did indeed always work to better than industry standards at the time, used up to date knowledge for the design & no evidence of negligence or criminal negligence was ever produced in relation to the DH Comet._*
The course of De Havilland & the general UK aerospace industry sector was not affected even slightly by the DH Comet.

It has a definite Thurderbirds look about it. Very retro-futuristic and sleek.
Great Video Thanks Paul.
wonderful
Flew to Majorca in a Dan Air Comet in 1974! A beautiful looking aircraft!
Great video, thank you
