HOUSTON - A flurry of reports from Russia about the discovery of fragments of an alien spaceship at the site of the 1908 Tunguska explosion may be nothing more than wish fulfillment by devotees of a half-century-old Russian space myth, or they may actually have been based on genuine spacecraft fragments � but of Russian origin.

It is generally accepted that the Tunguska event resulted from the catastrophic disruption of a large meteor high above the ground. Previous studies have yielded diverse interpretations as to the meteor's size, composition, velocity, and density before its arrival. Nevertheless, there is consensus that the disruption occurred 6 to 10 km above the ground, depositing approximately 15 Mtons of energy in a narrow altitude band. In a comprehensive analysis, Sekanina concluded that the body was not a comet, but rather an Apollo-type asteroid 90-190 meters across. More recent work has suggested that the object was a stony asteroid perhaps 60 meters in diameter. In contrast, Turco et al concluded that the meteor was of cometary origin with an effective density of 0.003 gm/cm3 and a diameter of 1200 meters.
As a meteorite slams into the atmosphere at speeds around 12 to 20 km/sec or more, it experiences a strong mechanical shock, like a diver bellyflopping into water. This can break apart stones of a certain size range, which explode instead of hitting the ground. Some of them drop brick-sized fragments on the ground, but others, such as the one that hit Siberia, may produce primarily a fireball and cloud of fine dust and tiny fragments. In 1993 researchers Chris Chyba, Paul Thomas, and Kevin Zahnle studied the Siberian explosion and concluded it was of this type -- a stone meteorite that exploded in the atmosphere. This conclusion was supported when Russian researchers found tiny stoney particles embedded in the trees at the collision site, matching the composition of common stone meteorites. The original asteroid fragment may have been roughly 50-60 meters (50-60 yards) in diameter.

People, this is crock. If the celestial body that crashed into Earth weighed that much, the whole continent would have been wiped out. Mind that they travel at 10+ thousand mph.
The asteroid would have been roughly half a mile to a mile in diameter if this were true. That would be the extinction of human race.
The Tuguska story looks bogus. It's a very amateurish hoax.

I still think the Tunguska explosion was caused from Tesla's electric gun. If you look at all the senerios and explanations of what went on - all the situations could be solved by an electric explosion.
Everything from what people saw, how the trees were knocked down in a butterfly shape, no debris until now. The rock, E.T. type thing found could have been from material solidify under intense heat.
