1977, Science and Technology: Space Shuttle Enterprise First Test

On February 15, 1977, the Space Shuttle Enterprise (OV-101) made its first three taxi-test (ALT-1 - ALT-3) on a concrete runway. The Approach and Landing Tests (ALT) were a series of taxi and flight trials to test the vehicle's flight characteristics both on its own and when placed on top of the Shuttle Carrier Aircraft. On August 12, 1977, the Enterprise made its first free flight (ALT-12) at 499 km/h. The shuttle was lifted to a height of 25,000 feet by a Boeing 747 and then released, gliding back to Edwards Air Force Base on its own. A total of 16 ALT flights were conducted in 1977.

Originally the first orbiter was planned to be named Constitution and would be unveiled on Constitution Day, September 17, 1976. A letter-writing campaign by Star Trek fans (Trekkies) to President Gerald Ford asked that the orbiter be named after the Starship Enterprise. Most of the cast of the original series along with Gene Rodenberry were guests at Rockwell's, Palmdale California plant for the opening. The Enterprise was a test space shuttle not intended for flights in space. It was used for test flights and public relations tours. The Space Shuttle Columbia was the first space-worthy orbiter, it made its first flight in 1981.
