<snip> Personally, I would like to see dampening fields used on airplanes (and in restaurants, movie theaters, etc.) that would render cell-phones and other similar transmitter/receivers completely inoperative. (That way, you could carry your personal electronics anywhere and still be able to enjoy dinner in a restaurant without having to listen to the person at the table next to you fighting with their boy/girlfriend over the phone.) The technology to do this exists. The challenge on an airplane is to implement it in a way that won't interfere with the aircraft's navigation and communications systems. <snip> I can't tell you the number of times that either my co-pilot (wife) or I have left our cell-phones active (live / on) while flying. They did not interfere with the Comm frequencies or the GPS navigational system nor the ground based nav systems (VOR/VORTAC, DME, Localizer, or ILS), or the transponder. Now the big iron pilots have Comm radios that operate on a higher freq set than our plane operates on (108-134? MHz compared to 4xx(?)MHz). As long as the dampening fields do not use 10MHz (First IF freq) or 400-48KHz (Second IF freqs), I don't see the problem. However, that would be the way to damp out those little buggers completely -- given what I remember of electronics theories.
