Exactly right helopat. Your scenario of dropping a raft and a smoke is one they considered (I won't yet say if that's what they actually did).
We were taught this scenario (and I taught it once or twice) and it's not a question of right or wrong (though if at the end of the day everybody's home and dry you'd be a bloody fool to not shout a round for the room and slap everyone on the back), it's a question of making the best decision based on the available facts. The various groups in CRM class often came out with different answers, but quickly exploring the available options and then acting upon them... that's a recipe for success.
