TSgt. Louis Jones and SSgt. Allen Jauw, 191st Maintenance Squadron, hook up hoses to an air regulator during a training exercise at Selfridge Air National Guard Base, Mich., Aug. 13, 20011. The 191st MXS performed an exercise in which they simulated a KC-135 Stratotanker had damaged nose gear and a crane was needed to move the aircraft to a safe location for repair. The air system was used to fill a series of bladders that could cushion the tail of aircraft while the nose of the aircraft was lifted by a crane. (USAF photo by TSgt. Dan Heaton)
