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.

The Air India flight, carrying 242 passengers and crew members, crashed shortly after takeoff from Ahmedabad, India, en route to London Gatwick.

Air India and Boeing are in the midst of significant turnarounds, but knowing the cause of the crash of Flight 171 will take a lengthy investigation.
