Qantas jet forced into mid-air return

A Qantas jet bound for Perth has been forced to return to Sydney Airport after a safety light turned on mid-air.

The Airbus A330 took off soon after 11am but was back on the tarmac by 12.30pm after an indicator light showed a possible issue with the rear cargo doors, a Qantas spokesman said.

"Engineers are inspecting the aircraft. There is no evidence at this stage of a problem," he said.

Passengers will be moved to another flight due to depart Sunday afternoon, he said.
