Witnesses say something not of this world crash-landed on a hilltop in the Russian mining town of Dalnegorsk in 1986. Metal fragments recovered at the site continue to puzzle scientists today. When subjected to heat, some of the elements "disappear" and are replaced by others. Some fragments display anti-gravitational properties.
Often called "Russia's Roswell," this amazing event is fully explored by former Soviet refugee Paul Stonehill, founder of the Russian Ufology Research Center, and British UFO expert Philip Mantle. In addition to complete analysis of the Dalnegorsk crash, the book fully covers the mysterious 1908 Tunguska Event in Siberia, which some people believe was an alien spacecraft that fell to Earth.
Other major Russian UFO cases are spotlighted, including sightings by Russian cosmonauts and members of the military.
