Static dischargers were developed by the US Navy when electronic communication and navigation equipment was first introduced on aircraft. Air friction on the fuselage causes electro-static buildup. Without the static dischargers this will reach a high voltage before dissipating into the surrounding air, causing 'sparks' that sound like crackling noises on the radios and disrupt navigation signals.
The static dischargers provide a conductor for this static electricity to flow off before a high voltage is built up.
No more sparks... clear communications!
We can't solve problems by using the same kind of thinking we used when we created them.
