What: Shanghai Airlines Boeing 757-200 en route from Shanghai to Hong Kong
Where: Shanghai
When: Aug 30 2010
Who: 131 passengers
Why: After takeoff, the air conditioning began smoking. Passengers were provided wet towels to breathe through to filter out the smoke; and oxygen masks were deployed, apparently unannounced. The smoke was dense enough to impair vision; and the crew attempted to use the fire extinguisher without success.
The flight returned to Shanghai, where emergency vehicles were waiting; and the flight made a safe landing at 11:53 am.
Most passengers were booked to Hong Kong on alternative flights.
