All across the USA we have cell towers, that handle millions of calls. It seems that it would be a small additional load to use them for general aviation. A way to do it would be that the towers, and flight facilities, would have a dual system that can recieve and transmit calls through existing air frequencies, or through cell towers. If a GA plane is only flown domestically, then maybe it could have only a 'cell' transmitter/reciever. I may have easily not considered something so, would like to hear ideas or info, that would take either side of the argument. I'm hoping for kind a brainstorming thread, so crazy ideas and observations would be acceptable, (untill shot down hard).
