If they can figure out how to use the particular radio, which was one of the
things the 9/11 terrorists screwed up despite reading the manuals. Hell, I
have enough difficulty switching among the various stacks in our rental
fleet of 172's. Is there a big red arrow labeled "PTT SWITCH HERE" in the
737?

Finding the PTT is easy. Trying to figure out where/how to select the frequency
can be daunting.
