You couldn't get the collective down and the power off and get some forward airspeed and airflow over the fuselage? What did you practice when you train for that scenario since I'm failing to see how it was unrecoverable.
Because the scenario they had is not the one in your head. I think their bad luck was compounded by landing on a small wall which ruptured the fuel tanks. It may well have been survivable up until that point.
