On June 12, a London-bound Air India Boeing 787 Dreamliner crashed soon after taking off from Ahmedabad, leaving only one survivor among the 242 passengers and crew on board. The aircraft slammed into a residential area, killing at least 38 people on the ground.

Investigators in India are studying the black boxes of a Boeing 787 Dreamliner after recovering them from the aircraft wreckage to ascertain the cause of last week's plane crash that left at least 270 people dead.

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.
