The doomed Air India flight that crashed last Thursday may have had an emergency-power generator operating when it crashed, investigators believe. The suggestion raises questions about whether the engine of the AI171 flight was operating properly during take-off. 

The plane crashed in a residential area only seconds after leaving the Ahmedabad airport. The preliminary finding, reported by the Wall Street Journal, comes as at least 270 people died in the crash, including 241 out of the 242 people on the plane and some on the ground in the Indian city.
