I was at an EAA Young Eagles event 20+ years ago where a kid try to get out of a Piper Cub 100' up. It was summer time, door was off, pilot in the back seat and the kid was 8 or 9 years old. Cub took off, started climbing, then the plane went all over the place kind of like the drunk pilot airshow routines. After a few seconds of that, he pulled throttle and slipped to a landing.
The pilot was white as a ghost when he parked. Apparently the kid just got scared shortly after takeoff and noped right out. The kid was half way out the door, and the pilot had to hang on to him with one arm while he landed. This was back when the YE program still had a zero fatality record that they were quite proud of. Pretty sure that was the last Young Eagles event at that club.
tbqh I don't know why you'd take up a child that isn't yours in an airplane with no door for their first time in a small airplane
