- I got this from "The Encyclopedia of UFO's", Ronald Story, ed.
-
- June 30, 1908, shortly after 7am observers at the Central Siberian
- Plateau near the Stony Tunuska River first saw a "ball of fire" coming
- over the southern horizon heading almost due north. Suddenly a
- "pillar of fire" short upward into the sky, which could be seen for
- several hundred miles. Enourmous black clouds rose 12 miles into the
- air, followed by a "black rain". On the following day, strange
- glowing clouds could be seen, at extremely high altitudes over Asia
- and Europe.
-
- Various explainations for the explosion, which devastated several
- hundred square miles of (furtunately unpopulated) pine forest have
- been put forward.
-
- * The original one, that of a meteor, was shot down due to there
- being no physical meteoric evidence to be found.
-
- * An alternative explaination was that of a comet entering the
- atmosphere and then violently vaporizing due to the increased heat.
- (The EoU calls this "the accepted, conservative view"). Since coments
- haven't been observed striking the earth before (or since) this event,
- it remains a possibility.
-
- * In 1947, the "spaceship theory" was put forward, that a
- spaceship's powerplant detonation had caused the devastation.
- (Or, alternatively, that the aliens detonated a nuclear device
- on purpose, for reasons of their own - I've even heard tell of
- "the war of the aliens", and such.)
-
- * Although not mentioned in EoU, another theory surfaced in the
- mid-1970's, that of a "mini-blackhole" (described by someone else in
- an earlier message), that actually passed through the earth.
- Unfortunately, no effects on the far side of the earth (waterspouts,
- or whatever) were witnessed (to my knowledge), so there's no extra
- evidence for this one.
-
- The EoU goes on in some detail, I'll just hit the high points:
-
- Points against the "spaceship" theory:
- * The fireball was far too brief, in comparison with what we
- know now about nuclear explosions, to be one.
- * approach trajectory of the object has been determined
- to be head-on with earth, which isn't really a great
- idea to do with a spaceship, so it seems unlikely that
- any self-respecting alien would do so.
- * there is no increase in carbon-14 in tree-rings that would
- account for a nuclear explosion in 1908 (this was asserted
- by William Libby, the 'father of the carbon-14 test', in
- 1976).
- * The recollections of witnesses was 20 years old before
- it was obtained by researchers.
- * spectrographic analysis (by astronomers) in 1908 showed
- that the "glowing cloud" was just dust, reflecting sunlight.
- * There had been a forest fire in 1888 in the same region,
- which accounts for descriptions of "rapid growth" in plants
- after the explosion; rather than being radiation-related,
- it was just due to nutrient-enhancement that happens to
- soil after a forest fire (and that the regions of
- "rapid growth" were in the areas of forest-fire, and not
- in other areas.)
-
- ... there's more, discussing further problems with "meteor" and
- "comet" theories, but this is a.a.v, and besides, you should find
- this book for yourself - try the library...
-
- I'll end with last line from the entry: "Whatever the actual
- cause of the Tunguska event, it has maintained a powerful grip
- on the popular imagination."
-
- Hope this helps,
-
- Charles

- There is one piece of evidence to support this. At the same time on the
- opposite side of the globe, a sea captain reported seeing a huge spout of
- water towering into the sky. An extremely dense object passing through the
- earth would be likely to pull some material along with it at the exit point.

- I thought this one had been put to rest over 20 years ago. The tektites in the
- area were the strongest evidence for the blast being the result of a bolide (a
- meteor that explodes before impact). The pattern of the falling of the trees,
- however, made an air burst of that sort unlikely. Testing of the results of
- air bursts, however, reproduced the same patterns in models. Accordingly, all
- the evidence points to a bolide, and no more unusual theory is necessary to
- explain the known facts.
