Lightning

Lightning is one of the most powerful and frightening of nature's forces. It kills at least a thousand people every year. It can be 30 miles long, but less than an inch thick. Meet people who've experienced its awesome strike firsthand. Follow a storm chaser whose photographs reveal its startling beauty. Enter a thundercloud and see how lightning is formed. Filmed in New Mexico and Florida's lightning alley, this program uses scientific experiments and breathtaking time-lapse photography to demonstrate lightning's enormous power.
