A mysterious explosion rocked the Jenissei portion of the Siberian forest. People living in the area observed a huge fireball that rose up high in the sky. Russian scientist Kazantsev researched what he described as the Tunguska blast, going so far as trailblazing through the area in search of an impact crater that was never found. Trees in the area, though, were knocked to the ground from an epicenter which, unlike normal blasts, was more elliptical than spherical, following the original object's trajectory. The witnesses who observed the fireball later succumbed to a deadly sickness very much resembling radiation poisoning.
Many theories have been suggested as to what caused the blast.
Most prevalent among those have been microscopic black hole impact with the Earth, collision with a comet and a nuclear powered extraterrestrial vehicle losing control and crashing.

Jun. 30, 1908 Podkamennaia Toungouska (USSR). Unexplained explosion in the taiga, equivalent to a thermonuclear blast, sometimes interpreted as the crash of an inter- stellar vehicle. (Anatomy 18; Challenge 99)
Web Link:http://www.cseti.org/crashes/082.htm At 7.00am on 30th June 1908 near the lower Tunguska River, Siberia, a large explosion occurred. The explosion was so massive that it caused damage 400 miles away, and was heard even further. Even the heat that came out from the explosion was felt hundreds of miles away.
For several nights all over northern Europe, the sky glowed enough to light the street of London. At first it was assumed that a massive meteorite had collided with the earth.
Given the remoteness of the area it was not until 1927 that an expedition was mounted to investigate the crash area. The expedition could not locate any bits of meteorite which puzzled them due the size that the meteorite would have to have been to create such a large explosion.
Another puzzle for the expedition was the way the tress were felled in an outward motion and that in the centre an area of trees were still standing, although all their bark and branches have been destroyed.
After the Second World War and the bombing of Hiroshima and Nagasaki, photos of the cities were compared with aerial photos of the Tunguska blast, and they were stunning similar.
As a result of this various scientists speculated that a nuclear explosion had taken place over the area, hence explaining the tree formation, and because no nation possessed nuclear device the logical conclusion was that it was from an exploding alien nuclear powered craft.
Other theories started to be banded around ranging from pinpoint black holes, and antimatter particles.
Many of the witnesses to the original crash spoke of seeing and oval-shaped mass moving across the sky, as well as seeing the object change course, and of having a very low speed.
Most people today believe that what hit Tunguska was simply a meteorite, but the alien craft theory still has a lot of credibility. As with most of these cases that occurred long ago, we shall probably never know for sure.
