People just do not realize, every single digital electronic device, including, believe it or not, many modern flashlights, emit radio energy. Yes, every single one! And no two are going to emit the same spectrum or power. If you drop your device, and damage it slightly, but not enough to make it unusable, you may change, significantly, the amount of radio energy it emits. In addition to the unintended, but still very real radio emissions, many devices deliberately transmit radio waves, including every wifi device, every Bluetooth device, every wireless mouse. Now, most people also do not realize that some of the signals airplane systems need to receive are very weak. GPS signals probably top the list. They are weak signals that require sensitive antennas and receivers to pick up at all. Modern airplanes are using GPS to guide you to the runway, down low to the ground, through clouds and rain when the pilots can't see the runway till you are only a few hundred feet up. Is this t
