Document Summary
People are often able to survive a lightning strike because the vast majority of the energy flows through the moisture on the outside of the skin and down to the ground. The buildup of steam in shoes or clothing can have explosive consequences, you may be blown out of your shoes. Airplanes are considered a safe place to be during a thunderstorm because metal is a great conductor of electrically, the lightning strike take a path of lesser resistance. Planes are composed completely of enclosed metal making it extremely safe for them. Physics: explain the reason why so many tornadoes touch down in the u. s. tornado alley each year. Two radically different air masses routinely collide here, in summer months warmer air moves north from the gulf or mexico. Two miles away cold air tumbles south from canada, to tornado ally. The difference between the death tolls was in 1999 44 people were killed and thousands where left homeless.
