Here's one maybe someone here could answer.
As I understand it cell phones are line of sight with the cellphone tower, obviously if you are in an area where your signal can't reach a tower you are out of communications. So let's say you are in the middle of nowhere with no cell reception and an aircraft flies overhead, one of the newer ones that are or soon will have their own onboard equivalent of a cellphone tower so the passengers can use their phone while aboard. Four or five miles below on the ground will your phone have the ability to interact with that plane, say in an emergency? I'm thinking they would shield it otherwise there would be random calls being picked up anywhere the plane flew.
Seems like an opportunity for the industry to make an emergency back channel for just such an emergency situation.

Anyone have some insight?

Cells phone on their own have an incredibly short range // 1 to 5 miles typically http://en.wikipedia.org/wiki/Cell_site and passenger aircraft these day are pretty fast.. 500+ mph that's 8 miles a minute, and they are usually at least 5 miles high to start with. Assuming commercial aircraft were even properly equipped .. the chances you would be in range for more than a minute if at all is extremely low.

Unless you were on flight 93, where the cell phones worked just fine......

If you have a Marine VHF hand held radio, you can , and folks often do, have distress calls answerd by passing airliners, whos radio's lock on distress channel use. Alotts Fex jets and such have helped many a lost and broke folks in Alaska. Cell phones are still in their infancy here.
