To quote someone 'It looks like he ran out of height speed and ideas all at the same time'. An impressive tribute to the aircraft structure that he walked away.
The pictures are amazing showing all of the structure deformation. That wing bends a lot in contact with the ground then looks like it returns to normal. I especially like picture 3, it looks like the old cartoons of the guy who gets his aircraft shot away around him and ends up flying through the air holding just the stick.
I know we are all supposed to run from crashed cars and planes since they all burst in to flames but why run from a glider? I think I'd just lie there
