I feel a little teensy bit controversial this morning and, of course, I've never had an engine failure...
but don't people think we sometimes get a bit over-obsessed -- and I include myself in this -- with safety matters and what to do in the event of XYZ disaster occurring? Too much anxiety can be as dangerous as too little and as a society we tend very much to the over-anxious -- safety at all costs! In everything! All the time! And sue somebody if something goes wrong!
Take reasonable, sensible precautions, don't sweat too much about what might never happen and, crucially, enjoy your flight.
