25 crew members on a British Airways flight were sent to hospital late Monday night suffering from smoke inhalation, when their jet was diverted to Vancouver International Airport.
With emergency crews looking on, the plane touched down at YVR at 11:35pm.
By 4am Tuesday, all 25 crew members had been released from hospital, and none of the 400 passengers was hurt.
British Airways is investigating the source of the smoke on Flight 286, and is arranging temporary accommodation and rebooking flights for the 400 passengers on board.
The plane was on a flight from San Francisco to Heathrow in London.
