Hay uno!!!
USAF C-130B was modified off the assembly line in Marietta, Georgia, as a prototype for a Short Takeoff and Landing transport for the US Army. This aircraft (#58-0712) was fitted with a boundary layer air control system that consisted of a wider rudder, single-hinged flaps instead of the standard Fowler flaps, and two Allison YT56-A-6 jet engines under the outer wings. Bleed air from the jets was blown over the flaps and rudder to enhance lift and controllability. First flown on 8 February 1960, this testbed was flown for twenty-three hours before the Army lost interest in what was to be designated the C-130C. The aircraft later served as a NASA research aircraft. [Lockheed photo]
