Atmospheric testing of Shuttle

Basic space shuttle launch and orbit configurations are examined. Particular attention is given to the atmospheric portion of reentry and landing, taking into account the pilot techniques, the flight control system, and questions of stability and control. Details are provided regarding a plan which has been proposed for testing the lower Mach number and altitude regime of the entry profile. The ALT program will be primarily concerned with gathering sufficient test data to verify safe subsonic aerodynamic flight and landing in the first orbital flight test approach and landing configuration.
