At around 7:14 on the morning of June 30, 1908, the sky above a remote stretch of Siberian taiga tore open. A fireball described by witnesses as brighter than the sun streaked across the basin of the Podkamennaya Tunguska River and, without ever touching the ground, detonated in midair. In an instant, roughly 2,000 square kilometers of ancient forest, an estimated 80 million trees, were flattened like matchsticks and splayed outward in a vast radial pattern that pointed back toward a single point in the sky.

The people who lived nearest the blast survived to describe it. At the Vanavara trading post, some 65 kilometers from the epicenter, a man named Semen Semenov was sitting on his porch when, he said, the sky split in two and the whole northern horizon seemed to catch fire. He felt a wave of heat so intense that he thought his shirt was burning, and an instant later a shock wave threw him several meters from his chair and knocked him briefly unconscious.
