*Returns from class*
What a clusterf-
Ooo, new page again! This year in aviation history, the De Havilland Comet is introduced to service as the world's first jet engined airliner. While being technically impressive, it's gained infamy early in its service life over a series of accidents where three of them broke up in the air. These crashes would eventually be attributed to rectangular windows, where the corners would be highly prone to metal fatigue after repeated pressurization and depressurization. An extensive redesign with oval windows solves the problem but fails to repair the plane's image, which sees dwindling sales until the last Comet 4 rolls off the assembly line in 1964. The last Comet in service is retired from commercial duty in 1981.
Note: No Comet 1s were preserved, since every single one was recalled by De Havilland for structural testing. The ones that weren't substantially damaged during testing were scrapped for liability reasons.
Note about the note: Structural testing of the Comet 1 consisted of dunking the whole plane in a pressurized water tank and subjecting it to severe pressure cycles.
Even more notes: One of the crashed Comets was G-ALYP - the third built, but first ever to be put in service. It was operating as BOAC 781, with the callsign "Yoke Peter."
