Staff Sgt. Michael Pratt, 14th Aircraft Maintenance Unit crewchief, reviews maintenance paperwork for an F-16 Fighting Falcon on the flightline during an operational readiness exercise Feb. 1, 2010, at Misawa Air Base, Japan. By keeping accurate documentation, Sergeant Pratt makes it possible for the next shift of crewchiefs to pick up where he left off. (U.S. Air Force photo/Staff Sgt. Samuel Morse)
