HOLLOMAN AIR FORCE BASE, N.M. -- An F-117 Nighthawk sits in its hangar after being repainted. The aircraft, owned by the 53rd Test and Evaluation Group's Detachment 1 here, was repainted gray as part of a test to determine whether the F-117 can have a role in daytime combat operations. Normally painted black, the stealth fighters are used for night missions. (U.S. Air Force photo by Airman 1st Class Vanessa LaBoy)
