A bolt of lightning dubbed a “megaflash” that shot nearly 500 miles across three US states has set the record for the most far-reaching strike in history.
The enormous bolt occurred in the southern US in April 2020 and extended 477.2 miles, or 768 kilometres, between clouds in Texas, Louisiana and Mississippi.
The rare low-rate horizontal flash beat the former record set in Brazil in 2018, by almost 40 miles.
