Cellphone use

The irrational prohibitions are those against devices that are not

air crews haven't a clue in this domain so they ride on superstition;
some airlines do the same.

Not irrational at all. Just because something isn't called a
transmitter, doesn't mean it isn't one. Laptops, GPS receivers, many
radios, are all inadvertent transmitters. Laptops because of their
onboard computer clocks at maniacal rates. Many types of tuners also
produce interference frequencies.

One of the most popular projects in 60s electronics magazines was for
non-transmitting (passive tuning) airline receivers you could use on a
plane.

Not to mention - how many people turn off their laptop's Bluetooth or
Wi-Fi when they're on an airplane?

It is an FCC rule because cellphone tower are designed to
pick up a limited number of calls and at altitude the towers
are over-loaded.

Except, of course, that very few people have cell phones anymore (at least,
as defined by the regulations that prohibit "cell phones" in the air).

Just because you are used to calling the thingy a cell phone doesn't make it
a cell phone.

But you never know. What if you use real cell phone and accidentally
overload some high-altitude tower? Who'll pay the costs? Tax-payers?
