I wouldn't have a clue how to take over a plane now, but I have flown a light aircraft twice in my life.
The first time, a friend organised a group flying experience, where half of us were going to get to fly a plan, and the other half just wanted to be flown around above Gloucestershire for a bit. In my plane, the two back seat passengers were both trying to get over a phobia of flying.
Having a complete ignoramus of a novice like me at the control can't have done much for their nerves, but I loved it.
The second time, my wife organised a flying experience for me. I was merely asked whether I had ever flown a plan before, so I was able to honestly say something like "Why yes, as it happens" (being a little economical with the truth). I was allowed much greater freedom, being allowed to taxi, take off, fly around and do everything until just before touching down. I thoroughly recommend everyone to try it at least once in their life. Stick it on your bucket list. If I am completely honest, however, it all got so much like driving in 3D that I would actually have forgotten all about putting the wheels down before landing!
