I just can't see what's wrong with a rotor blade touching the sea? In the 80s, we used to regularly give all the blades a quick dip during a shuttle flights to give them a wash. It improved performance taking off from undersized bow mounted low helidecks at night meaning we could ask for additional doughnuts and ice cream. If the "too heavy" light illuminated on the dashboard, we used to stick some blue tack over it to stop it becoming annoying.
What's wrong with today's passengers? They are going soft. I thought Canadians wore big boy pants.
I have been called as an expert witness.
