The crash of a 767 Lauda Air craft in 1991 was an important event in Mr. Lauda's life. It was his airline, and he was a trained pilot. He went to Boeing and demanded simulator time. He more or less proved that the aircraft had an equipment problem that pilots couldn't overcome. Boeing subsequently added safety features to its 737, 757,767, & 777 aircraft. As someone who had survived a near fatal race car crash, safety was of extreme importance to him. It appears that Boeing didn't learn a dam* thing from this incident. https://en.wikipedia.org/wiki/Lauda_Air_Flight_004
Just saw the special on that a week ago he was quite the man. After a crash and fire which almost ended his racing carreer he was back in a car and just missed I think two races. May he still be leading the race in fare weather and clear skies.
Niki Lauda's F1 crash is well documented he missed just 40 days of racing and considering he was given his last rights in hospital that's quite an achievement on its own. In 2018 he had a chest infection and was given a lung replacement which other than a post op infection was deemed successful. Sadly his death was not expected and at 70 not considered an old man. If you wish to know more about the man watch the film "Rush" which tells the story of his crash and recovery. His airline history is well documented too. RIP Niki.
