?

Lots of questions here. Just how scared was the digger operator?
Why use a digger in the first place?
What happens when he gets to floor level?
My guess is that he goes through the floor on one side, sits on the rubble and dumps out over the side of the building. If this is the case why hasn't he pulled the wall on the right in?
There is no obvious roll over or cab protection, so the operator was flirting with death anyway.
He has probably picked up a big hunk of concrete and reached out too far.
In any event I bet his life lashed before his eyes.
