How fast are you traveling?  Even if they could get a signal at high
altitudes, could the cell sites track the phone and keep up the
stream if the phone is passing through them at, say 500 mph?

I've wondered about that myself- cell towers are (AIUI) designed to
radiate mostly out, but not so much UP.  So we have a situation
where the planes are flying about two miles above the sites, at some
hundreds of miles per hour.

Not saying it isn't impossible, just surprised that it works.  I'd like to
see it tried.  If I didn't think I'd disappear to a secret CIA prison, I'd
try it on my next flight.  ;-)
