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.

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.

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.

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

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.

Boeing Co. Chief Executive Officer Kelly Ortberg finds himself in a familiar role — facing another crisis — this time a crash involving the company’s marquee 787 Dreamliner jet in India that killed more than 240 people.
