Air India pilot's reported cannabis test: What it can and can't tell investigators

Air India pilot's reported cannabis test: What it can and can't tell investigators Reports that an Air India pilot tested positive for cannabis after a flight sound like the sort of finding that should make an aviation investigator sit up. But the reported result has not been officially confirmed, and even a confirmed positive would not necessarily be the smoking gun it might appear to be. On 4 August, an Air India Airbus A320 flying from Phuket to Delhi suddenly lost about 91m (300ft) of altitude, injuring 13 passengers and four crew members. The aircraft, carrying 137 passengers and eight crew, landed safely in Delhi. The incident is under investigation.
