Lightning is a bright flash of electricity produced by a thunderstorm. Lightning kills and injures between 75 and 100 people every year - more than hurricanes or tornadoes. The highest death toll from a lightning strike was in 1971 when a passenger airline flying over the Amazon rainforest was hit by lightning, causing it to crash, killing 91 people on board.

閃電是由雷雨產生的一種強放電現象。每年因閃電而受到死傷的人數達75到100，超過了颶風或龍卷風的受害人數。死亡人數最高的一次是1971年，當時一架客機飛越亞馬遜雨林時受閃電襲擊墜毀，導致飛機上91死亡。
