The low altitude roll went terribly wrong

What happens in this video ?

June 4th 2011 – This biplane crashed in Nanaimo, Canada, during the Wings and Wheels air show. After several aerobatic maneuvers, a roll went terribly wrong and the plane fell and crashed in a grassy area to the east of the tarmac. The pilot has been seriously injured.

Surprised that the pilot was fortunate enough to survive. Looks like pilot error or partial lapse in consciousness. (Sounded like a woman's voice at the end, by the way, not a kid saying the "s" word?)
