2012 preview? Eyewitness accounts of the Tunguska comet/meteoroid impact in Siberia

I am impressed with the devastation that still exists at the epicenter of the Tunguska Event in Siberia. At the right, please find a photograph taken in 2008 from a helicopter showing how the impact area is still devoid of trees.

On the other hand, it is a swamp. Maybe that’s why there aren’t any trees. In any case, this helicopter photograph is a good example of the effect of the largest comet/meteoroid explosion in recorded history  100 years later.

I’m looking at previous end of the world scenarios for inclusion in my End of the World 2012 Movie. And, I’m also just interested in what eyewitnesses had to say about the event. For example, in a Wikipedia article called Tunguska Event, S. Semenov says that:

The split in the sky grew larger, and the entire northern side was covered with fire. At that moment I became so hot that I couldn’t bear it, as if my shirt was on fire; from the northern side, where the fire was, came strong heat. I wanted to tear off my shirt and throw it down, but then the sky shut closed, and a strong thump sounded, and I was thrown a few metres.

Also, Chuchan of Shanyagir tribe said that: 

We had a hut by the river with my brother Chekaren. We were sleeping. Suddenly we both woke up at the same time. Somebody shoved us. We heard whistling and felt strong wind. Chekaren said, ‘Can you hear all those birds flying overhead?’ We were both in the hut, couldn’t see what was going on outside. Suddenly, I got shoved again, this time so hard I fell into the fire. I got scared. Chekaren got scared too. We started crying out for father, mother, brother, but no one answered.
