Sydney:
An Air Canada flight was forced to return to Sydney airport on Thursday after crew members saw smoke coming from an oven in the galley, an airline official said.
No one on flight AC34 was injured in the incident, which forced the pilot to dump fuel before safely landing the plane in Sydney, said Jeannie Foster, Air Canada's general manager for Australia and New Zealand.
Foster said there was smoke seen by a crew member in an oven so the captain decided to return to Sydney to check it out as a safety precaution.
Foster said the captain had to dump fuel because it's a very heavy airplane with 15 hour's worth of fuel to get to Canada.
The flight, which was bound for Vancouver and Toronto, was carrying 264 passengers and later took off again safely.
Foster denied earlier reports of fire breaking out on board.
Australian air safety investigators said they were awaiting a report from Air Canada before commenting on the incident.
