on the plane listening no real utility, just asking for trouble. Before takeoff or to hear from maint. radios outside talking reason for delays of a flight while they tell you something else (huh? that's so much harder than juzt telling you the truth). Taking gadgets on travel most of time only worried about your loose or installed Li-ion batteries showing on xray, cool gadgets they dont even understand what they are looking at, so be polite while they do their job & offer to explain what they don't understand but clearly dont want to ask to avoid looking inexperienced to bosses. It's your job to follow rules & roll with it. Hope someone was joking about running coax for antenna suction cup to a window
on a plane- really? over the line
