Investors are looking for answers regarding the Air India Boeing 787 that crashed Thursday, killing more than 240 people.

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

Last year, the F.A.A. said it was also investigating claims by a Boeing engineer that parts of the fuselage, or body, of the Dreamliner were improperly fastened together, which the whistle-blower said could cause premature damage to the plane over years of use.

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

Air India plane crash investigators reportedly find the first of the "black boxes" from the Boeing 787-8 that slammed into buildings, killing all but one of the 242 people on board.

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.
