FS X NASA Space Shuttle. The shuttle has been modified so that it takes off and lands like a regular airplane. It also has slats and thrust reversers to help with control. It is extremely maneuverable, and can reach high altitudes as well as cruising at the highest speed FSX will allow. Built with FSDS, the shuttle has fully animated exteriors, including opening cargo bay doors. Also uses a custom panel featuring all custom XML gauges. By Andy Johnston.
