Pretty neat, wished it was fully completed and all but still cool.
I love the Orbiter simulator, hard as hell though. Will never be able to fly the shuttle, that thing is a beast.

Only made it to just over 45,000 Meters. Can't seem to get anything done with liquid fuel and an engine even after using boosters to get up; thrust from the liquid fuels just doesn't seem to do much of anything.

Nothing currently for Mac. They're working on it. Why am I not surprised.
