All you guys that want to get out GPS systems and stick Antenna to the windows with suction cups and trail wires all over your seats have you ever stopped and wondered what it looks like to other pax? In these days of heightened security where you cant even take a tube of toothpaste onboard ,they see a person doing this what are they to think? There first thought is not " look at that sad Anorak" but whats he up to? Why do you need to know where you are? As long as i know i am at least in club or higher and that the good looking hostie is only a yard or two away with my drink and that the entertainment button is at hand thats the only position i am concerned with!!!!!!!
