Mated to its Boeing 747 Shuttle Carrier Aircraft, Space Shuttle Enterprise goes airborne for the first time in the first of a series of “captive-inert” test flights. During these flights, there is no crew aboard Enterprise, nor are any of the test shuttle’s systems powered up; the flights are intended to make sure that the combination of the 747 and the Enterprise is capable of being flown safely. Further “captive-inert” flights are carried out over a ten-day period.
