Investigations into the Air India plane crash are looking into the pilot’s medical records, as it was shared that one of them was suffering from serious depression and mental health concerns.

Captain Sumeet Sabharwal was an experienced pilot and had close to 8200 hours in the cockpit. He was said to be piloting the Boeing Dreamliner when it crashed into a residential area and called 241 people on board and 19 people on the ground.

Seconds after it took off, two fuel switches inside the cockpit of the Air India flight were turned off, shortly after takeoff, and that led to a catastrophic loss of power and the plane crashing to the ground.

The switches had a locking feature, and that meant that pilots needed to lift them up before changing their position, as they are not simple push buttons that could be turned off by mistake or accident.

Now, investigations are turning to the mental health status of the pilots and searching through medical health records to find out whether or not he was fit for flying.

Captain Mohan Ranganathan, who is a leading aviation expert in India, shared how several pilots from Air India confirmed that the pilot had suffered from poor mental health. He even took time off from flying in the past three to four years, and a medical leave for it too.
