Well, it isn't quite a glider, but I figure skydiving is pretty close.
This photo is a still from my helmet-mounted GoPro that captures my
hands waving off everyone around me just before I deployed my
parachute. I was jumping with my team in Eloy, Arizona on Saturday,
and this is the view of our delightfully-barren landscape from above.
In the bottom left corner you can see the runway, and on the right
side you can see the vertical wind tunnel and one of the landing
areas. The focus of the picture is my altimeter, showing that I just
passed through 3,000 feet and should be thinking about opening the
parachute pretty soon. The picture quality isn't great, but I thought
it offered an interesting first-person perspective on the whole thing.
