Was the Boeing 787-8 Dreamliner that crashed over Ahmedabad seconds after taking off airworthy? When was it overhauled and maintained last time? Was there any issue with the engine? These questions are being asked the pilot sent the Mayday signals immediately after the plane could take off.

Investigators believe the Boeing Dreamliner had its emergency-power generator operating during the Air India crash in Ahmedabad.

The airline said this is part of its effort to support the victims' families both financially and emotionally during this difficult time.
