I know it's a little old, but I didn't see the last comments as being reckless and hazardous.
It was a training flight with a qualified instructor, and he wanted to demonstrate what would happen.
I figured he knew what he was doing, and it was better to do it controllably, instead of years later it happening unexpected without knowing the outcome.
Later he simulated a "yoke stuck failure" (no elevator and no aileron), suggesting that if I had difficulty in turning, I could've tried opening the door.
Interesting what JEP said, it also simulates a "stupid passenger".
Either way, I learned a lot that day.
