"Pilot action 100 per cent right, they tried to revive the engine that is further corroborated with the fact that there was some movement of the fuel cut-off switch," the former IAF pilot said.

A focus on the Boeing 787’s fuel switches in a preliminary assessment raised questions about the pilots’ actions, but much is still unknown about Flight 171.

Sumeet Sabharwal, 56, was the captain on the flight, while Clive Kunder, 32, was the co-pilot who was flying the plane. Together, the two pilots had more than 19,000 hours of flight experience - nearly half of it on the Boeing 787. Both had passed all pre-flight health checks before the crash.
