No, no, it was LTE, and definitely not the pilot's fault.....(where is that sarcasm emoji??)
Having seen how an inexperienced pilot can "chase" a swinging load and get 180 out of sequence with it, I feel that this is what happened here. The machine was physically moving around, not just yawing, to fling the load out to the side like that. Load got close to the trees, pilot flares and pedals away from it, starts to fly in the other direction (load accelerates away from trees), pilot turns again to stop that movement, and it goes to worms with the load people swung around almost horizontal. Amazing the loop didn't pop out of the sideways-facing hook of the 206. Tail rotor appeared to be working OK.
