All we see in the vid is the ac moving slowly from right to left of shot, with someone on the wire.
Now then, obviously its only going to be an opinion, but were they;
a. Approaching the pup with the person being lowered down.
b. Flying away from the pup with the person being winched up.
c. Trying to maintain a downwind hover but allowing the ac to stray.
d. Slowly approaching downwind, lowering the person and about to turn left for an into wind recovery.
… just before the rotations began?
Seems strange in such a strong wind to operate downwind and with the amount of other aircraft around, there must have been a pattern in operation around the ship.
