ShyTorque stated that they thought the aircraft was in a high hover
No, I don't think I used the phrase 'hover' at all. Single engine safety speed could be as high as 50 knots or so in those conditions.
I think the accident occurred on takeoff. An engine failed, the rotor RPM drooped and the alternators tripped off line. This caused the autopilot to drop out, destabilising the aircraft, which had insufficient power on the remaining engine to fly away. The pilot had no option except to attempt a landing back on the pad. Unfortunately the aircraft drifted back beyond the pad and crashed a few metres back from it. All on board were lost.
