Lightning is a flash of electricity in the sky that produces thunder after it strikes. It strikes the Earth millions of times per day. Ancient Greeks believed lightning was controlled by Zeus. Lightning causes forest fires that destroy millions of acres of trees each year. Pilots try to avoid flying through thunderstorms due to lightning risk, but commercial jets still get struck about once per year. The safety tips for lightning include going inside, staying away from overhead wires, and avoiding windows and doors.
