Air India Pilot Under Marijuana Influence Claims Sleep Medication
An Air India plane was flying from Phuket to Delhi when the nose of the plane suddenly dropped 300 feet.
That is like falling from the top of a very tall building in just two seconds.
Passengers who were not wearing seat belts were thrown up toward the ceiling right along with their bags.
About 20 passengers and four flight attendants got hurt.
After the plane landed, the pilots were tested for drugs.
The head pilot, called the captain, tested positive for marijuana.
The cabin crew said he was acting strangely, sitting on the cockpit floor and even trying to smoke inside the cockpit.
The other pilot, the co-pilot, had to fly the plane to safety almost all by himself.
The captain said he did not take drugs and was just taking medicine to help him sleep.
Investigators are still trying to figure out exactly what went wrong.
Air India flight AI-2379 plunged 300 feet over Odisha on August 4, injuring at least 20 passengers and four cabin crew members.
Pilot-in-command Sudeep Vashistha tested positive for marijuana in confirmatory psychoactive substance testing.
Cabin crew alleged Vashistha acted erratically in the cockpit, attempted to smoke, and had to be physically assisted back to his seat.
The post-flight maintenance report logged 13 system warnings and three failure messages, including hydraulic pressure drops and autopilot trip.
Vashistha denied using illegal substances, saying he was on doctor-prescribed sleep medication and had insufficient rest during a tight layover.

Air India's first statement described 'a brief in-flight turbulence-related event' and a 'momentary change in altitude,' and the airline later removed the word turbulence from its statements.
