U.S. lightning bolt leaps into record books at 768 km long

A single lightning bolt that leapt across three U.S. states has been identified as the longest ever, the U.N. weather agency said on Tuesday.
Dubbed a megaflash, the rare low-rate horizontal discharge covered 768 kilometres (477 miles) between clouds in Texas and Mississippi in April 2020. It was detected by scientists using satellite technology and its distance - beating the previous record by 60km - confirmed by a World Meteorological Organization committee.
"That trip by air(plane) would take a couple of hours and in this case the distance was covered in a matter of seconds," WMO spokesperson Clare Nullis said.
Another megaflash that occurred above Uruguay and Argentina in June 2020 also set a new record, as the longest-lasting at 17.1 seconds, the WMO said.
While these two newly cataloged megaflashes never touched the ground, they serve as a reminder of the dangers of a weather phenomenon that kill hundreds of people a year.
