This is a different plane from the Boeing 737 Max, which was in the headlines after fatal crashes in Indonesia and Ethiopia, which killed hundreds of people in 2018 and 2019 respectively. A software fault was found to have caused those incidents and the model was grounded worldwide for 18 months.

It’s also the latest disaster to hit the beleaguered American aerospace giant — which has been dogged by a door that blew off a 737 jet, a leaky spacecraft that stranded astronauts on the International Space Station for months, as well as politically damaging delays in outfitting the new Air Force One jets.

Fatal crash raises new concerns for both firms as they try to revamp after years of problems that marred reputations.
