f-sim space shuttle is available at the iTunes store. There is now a beautiful animation of the drag chute's deployment and release after you touch down (visible in the external views, normally seen in replays after you land, though I suppose you could land in the external view). The replay views are great, especially when you've done a decent landing. There is also an optional "windows in the sky" landing aid that I find more distracting than helpful (but it is probably helpful when you are first learning to land with the HUD visual cues). Excellent app. There is also an official video available here.
