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.

An investigation into a deadly crash last month has focused on control switches that cut off fuel to an Air India Boeing jet after takeoff.

Air India said that it had started voluntary inspections on 12 July, and completed them within the prescribed time limit set by the DGCA. The same was communicated to the regulator.
