LOS ANGELES (AP) — A United Airlines flight returned to the Los Angeles airport Monday about 40 minutes after taking off for an emergency evacuation after a reported fire, authorities said.

All flights at the LAX International Airport were ordered to remain on the ground for about half an hour during the flight’s return and evacuation, according to advisories from the Federal Aviation Administration. No injuries were reported.

The flight, which was en route to Newark, New Jersey, returned to LA to address a possible engine fire, the airline said in a statement. The LA Fire Department said it responded and the fire was contained as of an hour after the plane’s landing.

The flight took off at 10:43 a.m., began to turn around at about 11 a.m. and landed again at 11:19 a.m., according to flight tracker FlightAware.

The LA Fire Department said they assisted with the evacuation of more than 250 passengers and crew. Passengers exited the plane on the taxiway using slides and stairs and were taken to the terminal, the airline said.

The airplane was a Boeing 787-9, a variant of the popular line of 787 Dreamliner long-haul aircraft.
