The pilot-in-command of an Air India flight that suffered a sudden altitude drop of around 300 feet while flying from Phuket to Delhi last week reportedly tested positive for a narcotic substance in a confirmatory drug test conducted on Tuesday. The Air India A320, operating flight AI2379 from Phuket to Delhi on August 4, encountered severe turbulence during the flight, following which it abruptly lost around 300 feet in altitude. Following the occurrence, the pilot-in-command underwent a confirmatory drug test after an initial post-flight psychoactive substance screening returned a non-negative result requiring further analysis, according to an NDTV Profit report. "Currently, the doping test results are not out officially by the airline, so we will wait for the official confirmation. I won’t comment that the test is positive," he said.
