An Air India Boeing 787, the same kind of plane that crashed 4 days earlier, was forced to turn around after a midair "technical issue," the airline says.

Investors and the wider public are looking for answers after Thursday’s crash of an Air India 787 jet. Both of the plane’s black boxes have been recovered.

The incident follows the Air India crash in Ahmedabad when a Boeing 787-8 Dreamliner crashed minutes after taking off, killing 241 people onboard.
