Gregory Colyer demonstrates combat maneuvers in the T-33 during the 100th Centennial Celebration Air Show, June 10, 2017, at Scott Air Force Base, Ill. The two-place T-33 jet was designed for training pilots already qualified to fly propeller-driven aircraft. It was developed from the single-seat F-80 fighter by lengthening the fuselage about three feet to accommodate a second cockpit. (U.S. Air Force photo by Staff Sgt. Clayton Lenhardt)
