I was on a class trip out on Kjerragbolten in Norway. It is a rock wedged in a cracked mountain, leaving several hundred meters of freefall on either side of the rock. It was a particularily windy day, but somehow our teacher allowed us to walk out on it. I remember walking out on it, and getting basically scarred for life about heights, especially since the quick gusts that day could easily have killed me.

Here is a decent POV video of what I experienced (the video is not mine) https://youtu.be/VqzoC_C2RaI?si=BhECeXwgSu423RfJ

A few months later, our teacher left her position, and we never really knew why she left, but I assume some of the parents informed the board about her recklessness at that trip.
