"Shuttle" for the PC was released on two 360k floppy disks, however it could be copied to a single 1.44MB floppy and installed or run from there.Gameplay consisted of flying through simulations of a number of different space shuttle missions, starting with the Approach and Landing Tests where the original space shuttle, "Enterprise", was flown from the back of a modified Boeing 747 to a gliding landing at Edwards Air Force Base, through to launching the Hubble Space Telescope, building a space station, using the Manned Maneuvering Unit to capture satellites for repairs, and launching 'secret' military satellites.
