Remarkable.

The most realistic flight sim in the app store, period. This is the exact approach and landing that the shuttle flies (oops, flew). The developer nailed the shuttles HUD perfectly. Its not just some generic cut-and-paste HUD and flight profile like many sims throw in their half-baked shuttle add-ons (*cough* x-plane). This is an inch-perfect shuttle HUD reproduction.
The flight profiles are also beautifully accurate. You can choose different approach directions, HAC profiles, runway direction, and weather conditions. This allows you to actually recreate historical landing conditions and fly them as they originally did.
Because of all this, this app is also a major challenge. In the four years Ive had this app Ive made thousands of landings in varying conditions. It took a long time to be able to make consistent "good" landings, and even now "perfect" landings still arent a guarantee.
Simply put, this sim is remarkable.
A BIG Thank You to the developer and his team! And Im looking forward to that X-15 sim!
