An F-22 Raptor takes off from the runway at Holloman Air Force Base, N.M., Feb. 29. The F-22 cannot be matched by any known or projected aircraft, however, there hasn't been and probably will never be an aircraft designed that doesn't require care to fly its capabilities. The 49th Aircraft Maintenance Squadron, part of the 'Fightin' 49ers' at Holloman AFB, are responsible for maintaining a fleet of more than 20 Raptors worth an estimated $3.7 billion with a compliment of approximately 300 active and reserve maintainers.
