On June 30, 1908, a shockwave ripped through the remote Siberian taiga with the force of 185 Hiroshima bombs. It flattened 80 million trees over 2,000 square kilometers, yet left no crater. For decades, the Tunguska Event remained a mystery, fueling theories from antimatter to alien crash sites. This book sifts through the expeditions of Leonid Kulik and modern forensic astronomy to reconstruct the terrifying reality of a "megaton airburst." It explores the fragility of our planet in a cosmic shooting gallery and the sheer luck that this impact occurred over an uninhabited wasteland rather than a metropolis like London or St. Petersburg. A humbling look at the solar system's ability to reset civilization in a fraction of a second.
