The idea of a jet full of business travelers all yacking on cell phones worries me a bit in light of the fact that many modern A/C have no conventional physical connection from the cockpit to flight controls or engines. How much RF could the systems that control all the "Fly by Wire" controls take before they malfunction? Would the sheilding they have be enough to reject any harmful radiation that may develop? Has anybody ever filled one up with cell talkers and tested it? I for sure would start with a ground test first!!
