Russian Alien Spaceship Claims Raise Eyebrows, Skepticism

From the article:
An expedition of Russian researchers claims to have found evidence that an alien spaceship had something to do with a huge explosion over Siberia in 1908. Experts in asteroids and comets have long said the massive blast was caused by a space rock.
Unfortunately, this is a hoax, the spaceship bit. I've been interested in the Tunguska blast ever since I heard it mentioned in Ghostbusters. As cool the spaceship idea sounds to me, I believe Tunguska was an asteroid who didn't make it to the ground. This happens all the time. And sometimes, they go boom, sometimes big boom, big badda boom.
