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

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.

Indian authorities have ordered what they called “extended surveillance” of all Boeing 787 aircraft in the country’s fleet while they investigate the cause of the Air India crash.
