In reply to Stuart Williams:
It looks fairly straight forward but I think there's alot more to it than first appearances. The craft has to be orientated right in 3 dimensions (pitch, yaw and roll), coming in on the correct "line(?)" and at an appropriate speed. In short, being an astronaut looks to be a giant pain in the arse. The simulator gave me motion sickness too, as an aside.
I also wonder about how appropriate touchscreen technology is for piloting a spacecraft? Switches and dials can't crash.
