1976: The prototype space shuttle Enterprise is rolled out of its assembly facility in Southern California and displayed before a crowd of several thousand people. The Enterprise was built to perform test flights in the atmosphere and was constructed without engines or a functional heat shield, and was therefore not capable of spaceflight.
