I used to keep mine neatly folded in my boot pocket of my flying suit, always donned it on the the apron the minute i left the A/c and only took it off once away from the a/c and where no blind idiots operated i.e off the flightline, it costs nowt to wear one (only 10 seconds to don one) and one day you might be glad you were wearing it........
The fact you have asked the questions suggests doubt, so "if there`s doubt, then theres NO DOUBT"
