Windows

Two days out of the week I have long days at school, about twelve hours on campus. While I was waiting for my last class of the day I noticed the following. I've speeded up the video to make the effect the wind was having on these windows more obvious.

The last part of the clip is slowed down to normal speed so that I could provide some context to the problem. The windows are probably five feet tall and each pane is probably three or four feet wide. The hallway is a hundred feet or so. This is a lot of glass that doesn't seem to be solidly attached to the rest of the building. I have the distinct impression that the plate screwed into the window frame shown in this clip was added after installation.
