A real problem is not with the airplane, but also with the fact that
each cell phone on a plane will hit many cell sites and make a mess.

the ridges overlooking silicon valley. Lots of signal, but can't make
calls until you back away a few feet from the overlook (and masking
some of the sites). Being overhead is outside the design of the cell
Back in the late 80's with an analog cell phone in a private plane just
a few thousand feet up my friend made a call. Right after he hung up
the phone rang and it was the cell phone company. They asked him to
not use his phone in a plane. They said something about him lighting up
their system like a christmas tree when he asked them how they knew.
