The recent discussion reminds me of a question I've been wondering
about for a while.  How do the pay phones on airplanes work?  I assume
they must be some kind of cellular with a very large cell.  How many
cells are there nationwide?  What wavelengths do they use?  What
capacity does the system have and how much use does it get?  Who runs
them?  And, for that matter, why don't they interfere with the pilots'
radio communication?

Answers to these questions, or any others I may have forgotten to ask,
will be appreciated.
