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.

An Air India crash Thursday involved a Boeing 787-8 Dreamliner, which the aircraft manufacturer first delivered 14 years ago.

An Air India plane bound for London Gatwick Airport crashed shortly after take-off on June 12 in Ahmedabad, western India. Flight AI171 was carrying 242 people, including 169 Indian nationals, 53 Britons,

The passenger jet - the same type as the aircraft involved in last week's tragedy - was bound for New Delhi but landed back in Hong Kong about an hour after take-off.

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.

The investigation into Air India flight 171 crash opens up questions into the many concerns surrounding Boeing's 787.

The crash happened just weeks after the company cut a deal with the U.S. government to avoid taking criminal responsibility for a pair of deadly crashes in 2018 and 2019.
