I doubt we'll see this aircraft fly again. I know that I will never ever fly on this aircraft

The de Havilland DH 106 Comet was the world's first commercial jet airliner. Developed and manufactured by de Havilland at its Hatfield Aerodrome in Hertfordshire, United Kingdom, the Comet 1 prototype first flew in 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952.

However, within a year of entering airline service, problems started to emerge, with three Comets lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time. The other one was due to overstressing of the airframe during flight through severe weather. The Comet was withdrawn from service and extensively tested. Design and construction flaws, including improper riveting and dangerous concentrations of stress around some of the square windows, were ultimately identified. As a result, the Comet was extensively redesigned, with oval windows, structural reinforcements and other changes. Rival manufacturers meanwhile heeded the lessons learned from the Comet while developing their own aircraft.

Although sales never fully recovered, the improved Comet 2 and the prototype Comet 3 culminated in the redesigned Comet 4 series which debuted in 1958 and had a productive career of over 30 years. The Comet was also adapted for a variety of military roles such as VIP, medical and passenger transport, as well as surveillance. The most extensive modification resulted in a specialised maritime patrol variant, the Hawker Siddeley Nimrod, which remained in service with the Royal Air Force until 2011, over 60 years after the Comet's first flight.

The 737 Max 8 needs to go to the scrap yards before anyone else is killed.

I know I won't by on the 737 Max 8.

By the way what ever happened to the 727? I liked that aircrat

The pylon engines could be replaced with quieter versions but the central one that was integrated into the fuselage was unable to retrofitted to accommodate airport noise requirements and this led to it being replaced by the 737 and 757. I too thought it was a nifty looking aircraft, not Lockheed Constellation nifty, but still nice.

the Max 8 not so much.

to the wings and engines. It discussed why such an old design is being tweaked instead of starting from scratch which would make more sense from an aircraft design perspective.

The change in the engine placement changed the center of gravity affecting the performance of the aircraft. This required the MCAS system and software to overcome the tendency to pitch up and stall the wing. It seems to be just very badly cobbled together.

and money - bad mix

It worked on extra large fries, why not a tube traveling 500 miles an hour, at 36 thousand feet.
