In the wake of the Air India flight that crashed moments after take off last week leaving just one survivor, two other Boeing 787s turned around shortly after taking off on June 16, one from Heathrow and another from Hong Kong.

Air India Boeing 787 flight to London was canceled just days after the crash on June 12 that took the lives of over 290 people. Air India said the cancellation was due to "unavailability of the aircraft.

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.

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

India's aviation safety watchdog said on Tuesday surveillance conducted on Air India's Boeing 787 fleet did not reveal any major safety concerns, days after one of its jets crashed, killing at least 271 people.

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.

At least four separate flights encountered technical issues or emergencies within days of the Ahmedabad Air India crash, forcing sudden flight diversions and raising fresh concerns.

An Air India Boeing 787-8 flight headed for New Delhi returned to Hong Kong shortly after takeoff Monday because of a "technical issue," Indian media reported.
