Approach and Landing Tests

Trials of the prototype Space Shuttle Enterprise

The Approach and Landing Tests were a series of sixteen taxi and flight trials of the prototype Space Shuttle Enterprise that took place between February and October 1977 to test the vehicle's flight characteristics. Of the sixteen taxi-tests and flights, eleven saw Enterprise remain mated to the Shuttle Carrier Aircraft (SCA), while the final five had the shuttle jettisoned from the SCA, with the on-board crew flying and landing the spacecraft.
