That's a great catch on that shot - not something you see every day. As to how it happened? Well, sometimes stuff just happens...
I remember one of the first times I did spin training in the T-37 - I pushed the stick forward to break the stall, and the map case between the seats popped open, and various approach plates and nav charts bounced off the canopy and into our laps. Just when I was thinking "I'm going to get chewed out for that", the IP said "Damn, I know I checked that!"
