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.

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.

The black boxes will provide cockpit conversations and data related to the plane's engine and control settings to investigators and help them in determining the cause of the crash.
