It's the pilots fault the ground crew did not attach the line to one end of the litter in order to maintain control? It's the pilots fault the hoist operator stopped reeling in the litter when rotation wasn't enough to get airborne? With that presumption of guilt, I take it you sat in on the brief and heard all communications between ground personnel and aircraft. I agree if there was an available landing area within a couple hundred yards, a simpler and safer manual transfer would have been more prudent. Probably would have reduced fuel use due to no need for excessive flight/hovering waiting for ground crew to prepare. They as a crew screwed it up. If the pilot is/was in charge of training or specifically told personel to do something out of SOP, well then that's another story.
