A bomb scare on board a passenger airliner from China to Australia forced the pilot to abort the trip, an Australian television network reported on Tuesday.
A note warning that a bomb would explode on the China Southern Airlines flight from Guangzhou to Sydney was found one hour into the journey, the Nine Network reported.
The pilot took emergency action and returned to Guangzhou, said an Australian passenger.
"They dumped all the fuel. Then all the lights went out. But no one knew what was happening," said Jason Harper.
"Then we landed and there were about 20 police cars and fire engines and stuff everywhere."
The passengers disembarked from the plane and were interviewed by authorities for two hours before being allowed to re-board the flight and resume the journey, the network said.
