Flight tracking technologies

While cell coverage in a particular area
may not be enough to sustain a voice call,
it may be sufficient to transmit an ~100
byte data packet. Retries might be made
by the software.

The only way to find out for sure anywhere
is by flying the software and observation
of the updated flight path on the ground.

That said there's some giant coverage
gaps in the US West. We won't know until
somebody tries.
