Why don't voice radio communications use FM?

It's also the most frustrating. Hours to get to the airport, hours to
get past the paranoia of incompetent security staff, another hour to
get aboard, another hour waiting to leave the gate, a short period in
the air with tons of traffic all around, above, and below you, and
then another couple of hours at the other end.

Coudln't agree less. If, after that "short period in the air", I arrive
6000 miles from where I usually live, the exitment is all worth it. But
I take it you're not much into real life.

Actually, I agree with him on the "hours to get past the paranoia of
incompetent security staff". The rest of it is just hyperbole. But are
you really surprised?
