I once talked with the pilot of the 58T doing the Underslung Load....he said he was trying to get the aircraft to a cleared area and was accepting the yawing and once close enough to the clearing....he cut the Throttles...and entered autorotation and when he tried to move forward a bit....the nose dropped a bit too much and that is when it all went pear shaped.
He was not seriously hurt.....and he did opine he felt very badly about the damage to the aircraft.
