I wasn't expecting it to happen like it did. I thought for sure that bridge was going to give out on him and down they would go. Obviously there is a reason for digging over the blade and trying to do it from the side on a bouncy, home made bridge was why it flipped on him.
Since he was operating it on idle, it's pretty obvious that he wasn't experienced with the machine. In a way, that's probably what saved him and kept the machine from coming down on top of him.
Wish I thought he learned a lesson from it, but from the temper tantrum that he through, I'd guess that stuff like this happens to him all the time and it's never his fault.
