I would like to fly the Space Shuttle at FS9. What I've found was a freeware Add-On.. Thing is, I can fly it only without the external tank and the Boosters.
If I get it airborne with Tank and Boosters, FS9 will immediately stop working.
So, where can I get the Shuttle for FS9, which can be started like the real Shuttles? And which really works, without causing Program failures.
