Not to defend the idiots banging the glass, but I'm pretty shocked the entire pane fell out like that. Gotta think they should be better secured than that. Anybody know anything about how that works?
Sits between the stanchions and an aluminum piece snaps in on the front, holding the glass in place. As we see, the glass takes pressure very well from the ice side, but not very well in the other direction. The alternative is the "old" seamless glass which dropped into the boards somewhat, but was like running into a cement wall at speed (much heavier panes as well)
