CH-53 helicopter tail enter into resonance and break apart in flight

What happens in this video ?

The tail of this CH-53 helicopter enter into resonance while the chopper was performing a military mission at low level (the video shows clearly the strong vibrations on the tail). The chopper, out of control, crashed and burst into flames.
