[00:00:00]In 1908, the sky exploded over Siberia, and 80 million trees fell without leaving a crater. On the morning of June 30th, a fireball tore across the sky above the Tunguska River. Witnesses said it was as bright as the sun. Then came the flash, the heat, and a shockwave so violent it knocked people off their feet and shattered [music] windows far away.

[00:00:20]The blast exploded high above the ground, flattening a vast forest in every direction, but leaving [music] no impact hole behind. For years, the remote wilderness kept the mystery hidden. But when investigators finally reached the site, they found millions of trees lying outward from a center that looked like the sky itself had struck the Earth. More than a century later, Tunguska is still the largest impact event in recorded history.
