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.

Air India has finalized enhanced inspections on 22 Boeing 787 aircraft in its fleet following last week’s crash. The airline operates 33 Dreamliners, with the first acquisition dating back to 2012. The aircraft involved in the incident had been operational since 2014.
