Some things that appear dangerous are actually much less hazardous than their safer-looking alternative. Commercial airline travel, for instance, is 30 times safer than transportation by car. It may not seem that way to the person who would rather fight rush hour traffic on the ground than ride a solitary Boeing 747 at 35,000 feet. But out of 5 million scheduled commercial flights in 1982, only 5 resulted in fatal accidents. Being carried by tons of metal thrust through the air by huge jet engines is actually safer than being pulled along in an 8-cylinder machine that never leaves the ground.
