We have done it like that, here in Danish sector of the North Sea, since we began flying the S92. They started flying in the summer of '07.
Evey time I am HLO, and tell some poor chap to move forward, I think: "If this flight crashes. I have just doomed him to die..." Mind-boggling actually.
As far as I understand, the sole survivor of the Cougar crash had a window seat.
