Thanks, you're absolutely right of course.
The life jacket, inflated, would make a useful airbag substitute for a brace type landing though wouldn't it?!
I only mention this as on 6/11/09 I was LHR-MAN with BMI and had an aborted landing
VERY sharp, sudden ascent when we were 1-2 mins from landing, then went around 3 times. Captain said there had been bird strike ahead of us (feasible, as it was 5.30 ish)
I did start to wonder what sort of landing we were in for but it was OK.
Lots of screaming from other pax though!
While they were doing that, I was mentally re-checking where the exits where and making sure I knew how the door operated!!
