Float bags were inflated prior to water landing. Lots of coaning on main rotor blades - low rpm. That is clear as todays blue sky.
The thing that bothers me is, why did the pilot try to takeoff again if he was having problems.
Why attempt a SE water take off? There are plenty of ships handy.....he could have off loaded the pax or even burnt off fuel while sitting on the water.....or even elected to make a slow water taxi to suitable land?
... my point exactly.
