i have a friend who, until a few minutes ago, believed you couldn't use computers on airplanes because having them above a certain elevation would cause them to go haywire and intercept phone calls...i told him he was right, and if he ever sees anyone on a plane using a computer, to call a stewart/ess and have them throw it out a window.
