Are you coming over for the Heineken Cup final? Git....should have been Saracens there not your lot
.
Personally, I fly over water with a PLB and a gas bottle lifejacket. Blobby suits are ridiculously cumbersome and rafts a good idea, but I just cannot see how you'll get it out of a sinking hull in time.
Floats? Good idea, but another thing to maintain for the 0.05% of time that you need them, and I gather they quite often don't work. Anyway, we all campaigned not to have them a few years back!
But ask 100 helo pilots what they fly over water with and you'll get 100 different answers!
