Airbike, I'm curious as to what failed. Did the blade bolt shear? Did the blades holder separate from the spindle or did the blade holder fail where the blade bolt goes through? Maybe even another way? This is assuming there is enough left to tell what failed first.
I know I have done the same thing on a regular basis, the drained tank auto that is. Mine has never leaned out anywhere near that much.
