Wreckage recovered from the sea confirmed that the passenger windows were not related in any way with the catastrophic in-flight structural failures. Subsequent investigations revealed that the aluminum sheets on the roof were far too thin and weak and the AL2014B alloy was too brittle. The Comet lacked proper overlapping rip-stop doubler joints and the fuselage reinforcement hoops were too weak and spaced too far apart to prevent cracks from joining up with adjacent panels. The use of die cut holes and press form rivets was completely inappropriate and well below industry standards. An appalling number of manufacturing defects were found on completed aircraft and the quality control standards were very poor.

Wreckage recovered from the sea confirmed that the passenger windows were not related in any way with the catastrophic in-flight structural failures. The explosive cabin rupture was along the crown of the fuselage were de Havilland had used aluminum skins that were thinner than the rest of the pressure cabin. AL2014B alloy is too brittle for the application and the Comet lacked proper rip-stop doubler joints and the fuselage reinforcement hoops were too weak and spaced too far apart to prevent cracks from joining up with adjacent panels.

Also the aluminum sheets on the roof were too thin and all were made from AL2014B an alloy so brittle it's not used anymore. The Comet also lacked overlapping rip-stop doubler joints and the fuselage reinforcement hoops and stringers were too weak to prevent cracks from joining up with adjacent panels.

Composite aircraft like the 787 and A350 Have a predetermined cycle life when the plane must be scrapped due to deterioration of the resins and fibers. A well made Aluminum aircraft like the Boeing 707 series can have a potential unlimited service life with proper maintenance... the limiting factor here is cost.

The real tragedy of the Comet Disaster was that it could have been easily prevented if de Havilland had simply followed well-known and understood industry standards for construction of pressurized cabins made from riveted aluminum alloys. de Havilland simply lacked experience with these types of structures, in fact they were still making jet aircraft made primarily from wood and linen fabric at the time.

Indeed, the Comet Disaster was simply the result of egregious engineering incompetence and criminal negligence on behalf of de Havilland, these people has no business, and certainly no experience building jet airliners... these clowns were still building planes out of wood and fabric in the 1950s.

Metal fatigue was well-known and understood by the industry at the time... both the Royal Aircraft Establishment and de Havilland had received data on metal fatigue in pressurized cabins from the Boeing B-29 program during WW2.

No it wasn't, wreckage recovered from the sea confirmed that the passenger windows were not involved in the catastrophic in-flight structural failures. The Comet had aluminum skins that were too thin and brittle, lacked proper Rip-stop doubler joints and the fuselage frame hoops and stringers were too weak to prevent cracks from joining up with adjacent panels. de Havilland used riveting methods that were not appropriate for pressurized cabins and well below industry standards. de Havilland simply lacked the experience to build all-metal aircraft with pressurized cabins... they were still building aircraft primarily from wood and fabric

The amazing bag clip disaster was something to do with the wonderful video author be blissfully unaware of some very important facts rather incredibly.

There are very few photos of the Comet 1, half of them crashed in the first 2 years, the rest were chopped up and scrapped or modified into military transports.

I remember having seen a Nimrod on Air show in Berlin. It seems to be a military version of the Comet.

@engelbertkalkum8146 That's a common misconception that I once believed, the Hawker Siddeley H.S 801 Nimrod is actually a completely different aircraft, designed by a different company decades later and has no significant parts or sub-assemblies shared in common...

@@sandervanderkammen9230 Nimrod started as Comet 4C. The prototypes were even originally built as Comets. The rest was built new, and not modified passenger Comets, that is correct, but it was the same basic design. deHavilland became part of Hawker-Siddeley in 1959. (Later BAe)

@hepphepps8356 The Hawker Siddeley HS.801 Nimrod is not a Comet, it is a completely different aircraft from a different company, different factory decades later and has a different type certification. The Nimrod has different wings, engines, fuselage and empennage, and different avionics and ancillary systems. There are no significant parts or sub-assemblies shared in common.

They should have learned to build planes out of metal... de Havilland only knew how to build planes made of wood and fabric

That's not true, fatigue testing in pressurized cabins was well-known and understood by the 1950s, the truth is de Havilland lacking in experience with the design of metal aircraft and pressurized cabins made very high risk decisions and many egregious errors that could have been prevented if de Havilland had simply followed industry standards at the time. The truth is de Havilland was decades behind in aircraft technology and was still building aircraft primarily from wood and linen fabric... obsolete WW1 technology.

@@sandervanderkammen9230 That was my point; as far as I am aware the pioneering research done in airframe fatigue testing was by Arthur Wills of the Aeronautical Research Laboratory in 1947, presenting the results in 1949. Fatigue testing on the Comet started in 1949 under regulations set by the Air Registration Board, which were continuously being revised following research done by the RAF, with updated standards adopted by the ARB in 1953. De Havilland were following the industry standards at the time, but with fatigue testing of pressurised airframes being a very young area of research, these standards were continuously being revised.

@maidsandmuses *Junkers and Boeing were the world's leaders in pressurized aircraft and both conducted exhaustive research, development, and successful mass production during the 1930s, as did Douglas and Lockheed.* *The Royal Aircraft Establishment and de Havilland received technical data on metal fatigue in pressurized cabins from the Boeing B-29 program during WW2.* *Boeing by 1950 had produced over 5,000 aircraft with pressurized cabins, while de Havilland was still building aircraft primarily from wood and linen fabric when the Comet was in development.* *The Comet Disaster is conclusive evidence that de Havilland simply lacked the required experience and technology to produce a large all-metal pressurized aircraft made from riveted aluminum alloys.*

The Comet's engine configuration makes for a clean pleasing look. However, there are some drawbacks to the design. Turbojet engines like a clean smooth airflow to operate well. In a tight turn airflow to wing root mounted engines is somewhat negatively impacted by turbulence caused by the fuselage. The main wing spar (the part that gives wings their strength) has to pass by the engines close to the point of maximum stress, ie. close to the fuselage, this adds complexity and weight to the design. Another issue, especially with early turbojets, was engine maintenance, access is much easier with wing mounted pod engines. Lastly, wing mounted engines load the wing more evenly than root mounted engines, meaning the main spar is loaded less at the wing root and can be lighter. Having said all of that, it’s still my view that the Comet was a most beautiful, if sadly flawed, aircraft.

@petcatznz thanks for your detailed and informative reply. Aspects of design at which I would never have guessed. And yes you are right, the Comet did look good, even futuristic, but sadly not so practical.

*De Havilland designed the Comet based on a popular aerodynamic theory at the time that proved to be later found in testing to be completely wrong.* *The placement of the engine inlets in the wings leading edge proved to be a fatal flaw that is responsible for several hull loss accidents.* *No other aircraft manufacturers have ever copied this design flaw, it is widely known as an example of bad aerodynamic theory and practice.*

@@sandervanderkammen9230 thanks 🙂

The Canadian built Avro Jetliner, which first flew days after the Comet’s first flight, also had engines enclosed within the wings….. but not quite as fully enclosed as the Comet.

The real tragedy of the Comet Disaster was that it could have been easily prevented if de Havilland had simply followed well-known and understood industry standards for design and construction of pressurized cabins made from riveted aluminum alloys. The only lesson learned from the Comet Disaster was that aircraft manufacturers could no longer be trusted to conduct their own crash investigations (and de Havilland only had real experience in building aircraft made primarily from wood and fabric) The shape of the passenger windows had absolutely nothing to do with the catastrophic in-flight structural failures... this red herring was debunked when wreckage was recovered from the sea. Unfortunately, engineering incompetence and criminal negligence is responsible for the 492 innocent lives lost, a truly shameful and humiliating chapter in British history.

Wreckage recovered from the sea confirmed that the passenger windows were not related in any way with the catastrophic in-flight structural failures. de Havilland was negligent in using aluminum skins that were far too thin and an alloy that was too brittle. The Comet lacked proper rip-stop doubler joints and the fuselage reinforcement hoops were too weak and spaced too far apart to prevent cracks from joining up with adjacent panels. The design of the riveted fastners and the method of construction was inadequate and well below industry standards for pressurized cabins. de Havilland installed thicker skins on the roof section but the Comet modification were not enough to make the aircraft safe and its airworthiness certificate was permanently revoked.
