Test Cell
HOLLOMAN AIR FORCE BASE, N.M. – Tech. Sgt. Alan Woodall, 44th Aircraft Maintenance Squadron crew chief, speaks with Tech. Sgt. Raul Marrero, 49th Maintenance Squadron test cell technicians, April 19. Woodall was given the chance to see the way jet engines are tested first-hand because as a crew chief, he deals with jet engines on a daily basis. The F119-PW-100 jet engine is the primary propulsion system for the F-22 Raptor. (U.S. Air Force photo by Airman 1st Class Michael A. Shoemaker/Released)
