I also learned of this phenomenon pre internet when a friends Challenger broke a rear gear (8.75) and BOOM!! Stuff went everywhere. Wrapped the floor skin around his lower leg. Wiped out the gauges, small shards stuck in door panels. Needless to say blankets and billet drums became a must.

Cousins car a few years back at Vegas broke the gear (8.75) and shocked the sprag so hard it split the case.
