Authorities investigating the deadly Air India 171 crash that killed at least 270 last week believe the doomed flight was using an emergency-power generator, the Wall Street Journal reported on Wednesday, citing people familiar with the probe.
The preliminary finding has raised questions into whether the plane's engines were working properly during take-off.
The Gatwick-bound Air India aircraft, a Boeing 787 Dreamliner, crashed on a medical college hostel soon after taking off from the west Indian city of Ahmedabad last Thursday.
The Boeing was not much more than 400ft above ground when the two pilots experienced pilots onboard apparently lost power in both engines.
They then had 17 agonising seconds to wrestle with the controls before their state-of-the-art plane smashed into a medical college packed with doctors, sending a fireball soaring into the sky.
