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.

An Air India flight from Delhi to Zurich was delayed on Sunday due to mandatory checks on Boeing 787-8 aircraft, resulting in its late arrival in Switzerland close to the night curfew, sources said on Monday.

An Air India flight bound for New Delhi has returned to Hong Kong as a precautionary measure, after the pilot suspected a technical issue mid-air.

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.
