An airliner was forced to make an emergency landing in Lubbock after the pilot reported “fumes in the cockpit,” according to the Federal Aviation Administration.

An FAA spokesperson said on Saturday, United Flight 453, flying from Atlanta to Denver diverted to Lubbock Preston Smith International Airport “where it landed safely.”

There were no initial reports of any injuries.

Emergency crews responded to the airport, and checked the plane for damage and leaks, as first-responders were heard escorting passengers off the plane.

It was not immediately clear what caused the “fumes” on the plane, or how much damage, if any, occurred.
