Read this last weekend on the beach. Interesting. That poor bastard who put the life jacket around his neck at 30,000 feet and inflated it...

  To be fair, all the safety briefings I've seen tell you not to do that. ("Do not inflate while inside the airplane" is the line, I believe).

    Most people assume that's just a precaution to make it easier to move around the cabin and not a choking hazard!

      Massive part of the reason is because if the airplane ditches into the water, the life jacket can make it very difficult for you to escape [1]. https://en.wikipedia.org/wiki/Ethiopian_Airlines_Flight_961 https://en.wikipedia.org/wiki/Ethiopian_Airlines_Flight_961

        I assume that the pressure differential between sea level and 30,000 feet is going to change how inflated it gets as well
