Did a trip to the pole(true) in my mil days. We took 3 navs and used grid navigation that involved making a false pole somwhere else and forming a grid from that point. then when you get to the real pole you dont have to ask which south? When flying in northern canada near the mag pole.All the beacons are aligned to true wich makes for interesting instument readouts. The neadle points one way when the beacon is in the other and the standby compass is trying to point down!!!
