Weather Proverbs, True or False? The new eight words you cant say on TV. How to put a ship in the bottle. Welcome to toothpaste world.
Most commercial airlines flights avoid the turbulent center of thunderstorms by flying over or around them. Perhaps more importantly, all commercial airplanes are outfitted with protective equipment. The shells of airplanes are generally made of either aluminum (an excellent conductor of electricity) or composite that contains conductive fibers so if the plane is struck, the lightning travels along the exterior of the plane then out into the open air. Sensitive electrical equipment is shielded with surge protectors and grounding devices.
On average every airplane in the United States is struck by lightning at least once a year. Lightning strikes have been implicated in only a handful of crashes worldwide. Lightning hasn't caused a U.S. airliner crash in about 40 years. More facts . . . Michigan drivers: Take a look at this site:
