helimutt: shame on you! You do not need to "smash into a crane" (is that meant to simulate journo-speak or something?) to then "spin wildly out of control and fall over the side". I made mention in my first post to the BIH S-61 and the Brent Spar. No one suggested they "smashed into the crane" but they sure as hell span wildly and fell off the edge - read the AAIB report and see how much of a non-event you consider tail rotor to crane contact is.
I'm with T4 (et al) on this ; I'm just aghast that any right minded professional offshore pilot considers it a non-event (or minor event) to stick your tail into a crane!
