'Jeopardy!' celebrates Air Force's 60th anniversary
Airmen from the 27th Fighter Squadron at Langley Air Force Base, Va., speak with Alex Trebek, host of the TV game show "Jeopardy!," as he sits in the cockpit of an F-22 Raptor at Kadena Air Base, Japan, in March. Mr. Trebek and his crew were on a USO tour and taped video clues at various base locations in honor of the Air Force's 60th anniversary this year. Other aircraft featured in the clues included the F-15 Eagle, KC-135 Stratotanker and the HH-60 Pave Hawk. (U.S. Air Force photo)
