A FedEx cargo plane made an emergency landing at a busy New Jersey airport on Saturday after a bird strike caused an engine fire that could be seen in the morning sky.

The plane landed at Newark Liberty International Airport during the emergency, said Lenis Valens, a spokesperson for the Port Authority of New York and New Jersey. There were no reported injuries, and fire on the cargo plane was contained to the engine, Valens said.

Audio recorded by LiveATC captured a person calmly saying the aircraft needed to “shut down for a possible bird strike” immediately. “We need to return to the airport.”

Moments later, another person is heard saying: “We believe we saw their engine fall off the right wing.” The audio indicates the strike happened when the plane was several hundred feet off the ground.

The emergency landing caused air traffic to be briefly halted as a precaution, and operations resumed shortly after, Valens said. The emergency landing happened just after 8 a.m. Three people were on board, and all got off the plane safely, Valens said.

The Federal Aviation Administration said it will investigate the incident. The FAA said in a statement that the “strike damaged one of the Boeing 767’s engines.” The National Transportation Safety Board also said it would investigate.

Bird strikes are aviation hazards that sometimes cause major disruptions. Birds were blamed for bringing down a jetliner that “Sully” Sullenberger landed on the Hudson River in 2009.

The FAA has said bird strikes are increasing, with more than 19,000 wildlife strikes at 713 U.S. airports in 2023. Only rarely do they cause so much damage that jetliners are forced to make emergency landings.
