The purpose of the book is a dual one: to detail the nature and results of Tunguska investigations in the former USSR and present-day CIS, and to destroy two long-standing myths still held in the West. The first concerns alleged “final solutions” that have ostensibly been found in Russia or elsewhere. The second concerns the mistaken belief that there has been little or no progress in understanding the nature of the Tunguska phenomenon. All this is treated by the author in a scholarly and responsible manner.
At 7.14 a.m. on 30 June 1908 a huge fireball exploded in the Siberian sky. A thousand times the force of the Hiroshima bomb, it flattened an area of remote Tunguska forest bigger than Greater London, forming a mushroom cloud that almost reached into space.
