Wunper: Thanks for the correction and the link, I missed that one because I do not venture in Rotorheads very often.
The two chaps who were rescued were both fairly big and heavy.
Having lifted the pilot out of the water the poor chopper did not have enough power to hoist the nav straight up, so it had to get some forward speed first.
The nav said he was flying through the water with his arms pinned back, giving a good imitation of a destroyer at full speed.
