As a child 60 odd years ago I witnessed the daredevils amongst us swing on park swings which comprised of wood seats and chains gain enough momentum to go completely over the top. A guy has posted on Physics-Astronomy that he believes it is not possible and I have not recalled this properly.  I have questioned several of my friends and they remember it too. I don't know physics I just am learning about astronomy at this late stage in my life. How can I convince him this is true in a simple fashion because I truly witnessed this happening many times?
