I wish I had taken a photo but I didn't. When I parked for the evening after a day on the road, I noticed that the emergency exit window in the loft was hanging on by less than 1/4 of the frame. Looks like the rivets on the front of the hinge let do and the window came out. Couldn't have been there for very long or it would have blown away.
I more or less forced the glass almost back into place and with a lot of gorilla tape it stayed there for the two more days travel to get home.
When I feel energetic enough, I'll pull the exterior frame and see if things can be fitted back together.
I recommend checking the rivets on your windows so you don't have the same problem.
