I wrote this on another thread, but I think it's worth posting here again:
When the hijacked Ethiopian 767 crashed off the coast of Africa it became clear that a number of the passengers had...despite being told by the captain minutes before impact NOT to inflate their life jackets...done just that: inflated their life jackets inside the cabin.
The results were predictable, when the plane hit the water it filled so quickly passengers had to dive under water in order to get to the exits. Those who had not inflated their life jackets could hold their breath and dive for it. Those who had inflated their life jackets floated to the top of the cabin and were trapped against the ceiling.
Listen to the safety briefing, it might one day save your life.
Lord Lucan, I'm sure you do know the brief off by heart...and I'm sure you'd do fine in an emergency (not that I approve of not watching the briefing...I think it is rude not to listen and as I said above it could save your life)...but honestly one must question the sanity of someone who admits to not listening to the briefing on here, I mean you must have realised you were going to get a broadside a la PPRuNe when you first posted.
Forgive me for saying this but it just sounds like a wind up.
