Look at the frames from 1:30 seconds to 1:56 seconds in the clip listed above. To me, it looks like he dumped collective with nose low to gain airspeed in the beginning... and made an excellent recovery. I'm guessing, but since he didn't have many landing options - he probably tried to bring power back for the safety of those below. Nicely done, indeed. No fire, but I'm amazed at how easily the tail section broke off like that!
