Rules Written in Blood

A known design flaw in the DC-10's cargo door, left unfixed by the manufacturer, led to one of aviation's deadliest disasters. In 1974, the door blew off Turkish Airlines Flight 981, causing an explosive decompression that collapsed the cabin floor and severed all flight controls. This catastrophe, which killed 346 people, was a repeat of a nearly identical incident two years prior, exposing a pattern of corporate negligence that was only stopped by a mandatory federal order.
