One of the unique flight experiments uses smoke generators and yarn tufts for flow visualization. The aircraft completed 385 research flights and demonstrated stabilized flight at angles of attack between 65 and 70 degrees using thrust vectoring vanes, which directed engine thrust for control, and a research flight control system. Later in the program forebody strakes were added. Strakes are hinged structures on the forward side of the fuselage to provide control by interacting with vortices, generated at high angles of attack, to create side forces. This combination of technologies provided much improved handling of a fighter aircraft in a part of the flight regime that was otherwise very dangerous.
