The trade event is a big draw for the industry every year, as Boeing, Airbus and other aerospace giants host parties, sign deals and show off new aircraft.

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.

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 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.

Air India said it has completed such safety checks on nine of its Boeing 787 aircraft and is in process to complete it for the remaining 24 planes.
