Maybe I am biased after seeing what was left of a guy in a R22 after the main rotor cut the boom off.

The main rotor cut the tail boom off? Sounds like pilot error to me....unless it was a failure of the rotor hub and/or shaft. There are only a few instances that the main rotor can contact the tailboom(barring any mechanical problem)....low RPM and full/rapid cyclic/collective movement....low G/negative G conditions in flight(which are prohibited in the R22 anyways, due to some inherent problems with the style of rotor used)...and rapid control movement when the rotor is either spinning down or just starting up.

What exactly was the scenario during which this occurred?

about 7 yrs ago but i think it was in cruise on a windy day. I'll try to find the NTSB report. (I have zero rotary wing logged time. )
