This afternoon, Eli and I gave aerofly FS [$6.99 (HD)] a spin. It's a flight simulator, and a port of a PC and Macintosh game that goes by the same name. I think we had a good time. I landed a plane for the first time and nothing caught on fire. Also, there was no panic.
In practice, FS plays a lot like X-Plane. In fact, the UI and control designs are pretty similar, too. Tilt controls handle the all major movement, while toggles on the side of the iPad handle thrust, your flaps, and other stuff. Not that you need to worry about a crash. Turns out there's no crash animations or physics. So, there's that.
If you've been looking for another flight sim, this might be up your alley. It has a lot of smaller planes, but the F-18C was definitely an interesting ride. Check it out:
