I seem to recall that this wasn't so, early in cellular history. Weren't
we
able to use cell phones on flights, long ago?

Is cell phone usage also restricted on private jets, etc. for similar
reasons?

So my question... what is the technical reason for restriction of cell
phone
us on commercial flights? Is this reason valid, technically? Or is it
simply
an excuse to force anyone who needs to make a call to use the airline's
on-board phones (and pay their outrageous rates)?

The origin of the ban was due to concerns about cellphone transmissions
interfering with onboard avionics. This is more likely to be a concern
with older
a/c. There is no hard data that I know of that substantiates the concern.
There
is some anecdotal evidence of interference though.

Everyone's got a conspiracy theory. Here's another: The ban on cellular
phones is kept alive by the book publishing industry. Some in the evil cabal
may actually have the best intentions: Trying to get cell phone addicts to
shut the phuque up and try reading something for a change.
