I can put on a life vest blindfold,
Can you do this just from the safety briefing, or have you been given supplementary training?
I booked myself on a BA course, where we all had the chance to try on the safety vest. Despite having watched the safety briefing carefully many hundreds of times, all attendees found that it was much trickier than we expected. Even young and athletic oil-rig workers found themselves sticking their heads through the armhole.
Quite how passengers are expected to do this in a crisis situation is an interesting question.
