Wichita ? One passenger was slightly injured Wednesday night after an Allegiant Air MD-80 lost one of its engines and had to make an emergency landing in Wichita.

Allegiant spokeswoman Sabrina LoPiccolo said the charter plane was flying 125 passengers from Pittsburgh, Pa., to Laughlin, Nev., and had stopped at Mid-Continent Airport in Wichita to refuel.

She said that after the plane resumed its flight, passengers heard a loud boom at about 1,500 feet and the pilot returned to Wichita.

LoPiccolo said one person was slightly injured while coming down an emergency slide. She said most of the passengers used the plane’s stairs to exit, but 15 used the slide.

Officials believe the left engine failed; LoPiccolo said there was no indication of a fire.
