18/02/1977 Space shuttle orbiter is tested in flight for the first time

American space shuttle Enterprise was tested for two hours on the the top of a modified 747 jumbo jet. It was the first of five flights in the nine-month-long Approach and Landing Test testing program. Enterprise lacked engines and functional heat shield, and was therefore not capable of spaceflight.
