Since the Space Shuttle will need to be transported from its place of assembly to the launch site, a method has been developed whereby the Shuttle rides piggyback on a modified Boeing 747, called the Shuttle carrier aircraft (SCA). This paper describes tests of the SCA in its mated configuration. Tests include: flutter, found to decrease when fiberglass and wood fairings were added to the base of each supporting pylon; stability and control, found to be acceptable after damping with control pulses; noise and buffet, found high but acceptable; and climb, in which drag was marked but acceptable with the special rated thrust (SRT) power setting. Simulated launch maneuvers were undertaken at an airspeed of 273 KCAS. Transport of the Shuttle takes place with the Shuttle tail cone on, at a cruise speed of 288 KCAS at an altitude of 22,000 feet.
