There was no wind. The red flag is not flapping until the rotor wash hit it. Before and after it is calm. No ripples on the water,smoke goes straight up. If that is the ocean and not a lake at altitude, they should have had heaps of power at sea level with only 2 ppl on board.
I understand it was some larey sh#t flying but was the high rate of decent no airspeed at the end intentional and the clincher ?
