True but I recall a story some years ago...Mid 70's...where a downed wessy 3 crew ditched (as they usually did)...and the sea state was 5 gusting 6. The crew jumped into their liferafts and along came the SAR helo to rescue them...(another Wessy 3 - alarm !!! )
The crewman was first and he grabbed the strop and up he went. The Pilot was next and although the strop was in front of him it hadn't earthed and he missed it.... SAR crew were struggling (remeber the wessy 3 FCS - Alarm again) and eventually they decided to overshoot and go round for another try. Round the circuit and they lost the survivor....Never saw him again. And that is why, if I were in my single seat and the strop was in front of my face I'd grab it and take the belt.
