A squad of his comrades wet down Col. Greg "Happy" Gilmour after his final flight as a member of the 931st Air Refueling Squadron. The wetdown for flyers' final flights is a military tradition. Colonel Gilmour was selected to be the operations group commander for the 931st's parent wing, the 507th Air Refueling Wing at Tinker Air Force Base, Okla. (Courtesy photo)
