I did an intro flight a couple of years back. It was a lot of fun. They did let me takeoff. He said it was a little too windy when it came to the landing though, so he took over.

Hardest part was adjusting that little scroll wheel thing (sorry, forget what it is called) to keep the nose of the plane pointing the proper amount of up vs. down when you are in the air. If I recall, when it is adjusted correctly you can just about let go of the controls and fly straight and level.
