The captain of an Air India flight from Phuket to Delhi, which unexpectedly lost about 300 feet of altitude last week, has tested positive for marijuana in a follow-up drug test, according to an informed source. Earlier today, India’s Civil Aviation Ministry summoned Air India CEO Campbell Wilson regarding the incident, involving an Airbus A320neo aircraft, as another source revealed. Neither Air India nor the ministry responded to requests for comment. The flight, carrying 137 passengers and eight crew members, experienced a brief altitude change over Odisha, an eastern Indian state. Air India claimed it had not yet been informed of the results.
