There is something worth to mention here... add also static electricity to the posible causes of major disruption of communications: During 1990, in operation Desert Storm, the modern Solid State equipment used by the Armed Forces was damaged due to strong desert sand storms. Static electricity built up on their antennas burning out the RF amplifiers on their radios. Collins KWM-2 transceivers (vacuum tube thermionic radios from the 60's-70's) were brought back into action in an urgent rush call to supply the need of communications for the Armed Forces. Thousands are still in use today by ham radio operators world wide.
