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.

By Tim Hepher, Paul Sandle, Joe Brock and Giulia Segreti PARIS (Reuters) - Airbus secured more aircraft orders on Wednesday, raising its total to $21 billion at this week’s subdued Paris Air Show, while rival Boeing opted not to announce new sales following last week’s Air India 787 crash.

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.
