BRIDGETON, Mo. (AP) — A spokesman for Lambert-St. Louis International Airport says no one was injured when a fighter jet made an emergency landing that forced the brief closure of a runway.

Jeff Lea says the Boeing F-18 jet landed safety about 6 p.m. Thursday.

Lea says the plane was having mechanical issues, and that a wire system on the runway had to be deployed to help stop the plane.

It’s not immediately clear if the plane was being flown by a Boeing employee or by someone with the military.
