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.

Aryan Asari just wanted to film planes flying in the sky - but he ended up capturing one of the country's biggest air crashes.

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.
