The crash of an Air India Boeing 787 Dreamliner seconds after takeoff from Ahmedabad city, killing all but one of the 242 people on board, is the world's worst aviation disaster in a decade. At least 30 people were also killed on the ground as the airliner crashed into a medical college hostel near the airport.

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.

An Air India pilot turned back his Delhi-bound Boeing 787-8 Dreamliner to Hong Kong airport as a precaution shortly after taking off on Monday, citing a technical issue, Indian media reported. Flight tracking data showed the pilot turning Flight AI315 around less than 30 minutes into the flight from Hong Kong.
