Take on the flotation device

I've been on hundreds of flights but it wasn't until today that I
heard a little subtlety in the Delta safety video. After explaining
how to fasten a seatbelt, telling you about their frequent flyer
program and showing us some terrible promotional video they hit us
with probably the most important piece of information. As they
discussed a possible water landing, I clearly heard the video say
that 'some chair cushions' could act a floating devices. Some cushions
is not the kind of information I want to have to find out when I am trying to
swim in minus 20 degree weather, I saw the way Titanic ended and
without a raft you are screwed. Call me a socialist but to me you
either offer everybody a floaty or nobody one because the last thing I
want to find is that my seat cushion is the equivalent of a bowling
ball

Thank god this particular flight is all over land.
