American Airlines flight from LAX to Sydney makes dramatic U-turn while flying over the Pacific

An American Airlines plane had to turn back just half an hour after takeoff and make an emergency landing back where it started.

Flight 73 took off from Los Angeles at 10.30pm on Wednesday on its way to Sydney, but made a U-turn over the Pacific Ocean at 11.02pm, according to flight data.

The Boeing 777-300ER plane safely landed back in LA at 1.50am with no injuries reported.

American Airlines said the issue was a false alarm and there was never any danger to the flight.

The crew noticed an indicator light warning of a problem with the cargo bay door and immediately turned back to LAX.

However, when the plane was examined, maintenance workers found no problem with the door and the light malfunctioned.

Flight 73 will take off at 1pm on Thursday with the same aircraft.
