In 1908 a blazing fireball descended from the sky and devastated an area about half the size of Rhode Island in the wilderness of Tunguska, Siberia. It has been estimated that the explosion was equal to more than 2,000 Hiroshima-type atomic bombs. Although for many years scientists thought it was probably a meteor, the lack of evidence has led to numerous speculations ranging from UFO’s to Tesla Coils and to this day no one knows for sure what caused the explosion.
