A Frontier Airlines flight struck and killed a person while taking off Friday night, sparking a partial engine fire and forcing the plane to stay grounded.

Pilots aboard Frontier Flight 4345, which was bound for Los Angeles International Airport, reported striking a “pedestrian” while taking off from the runway at Denver International Airport at 11:19 p.m, according to airport officials.

The unidentified person was at least partially sucked into one of the engines of the Airbus A321neo, which ignited the brief engine fire, ABC News reported, citing sources.
