Lightning is a familiar sight in stormy skies, but a new report has revealed just how far some bolts can travel — in one case, more than 500 miles.

The 2017 “megaflash” stretched from eastern Texas to near Kansas City — a distance that would take at least eight hours by car or 90 minutes by commercial plane, according to the World Meteorological Organization. In comparison, the average bolt of lightning usually measures less than 10 miles, according to the National Weather Service.
