What happened

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

Why it matters

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.

Common ground

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.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
