That used to happen so frequently with Formula air racers where they chopped
the props for the O-200's to get the RPM up to get additional HP out of that
little engine that they started using a safety cable around the engine.
That way when the prop shed a blade and the engine jumped out of the engine
mount the cable held it somewhere near where it was supposed to be so you
could get the airplane on the ground in a survivable fashion!
Not something you want to play with normally.
