...but not from who you would expect:

Members of a Russian scientific team researching the site of the Tunguska meteorite crash of 1908 say they have found remnants of an extraterrestrial spacecraft, report a variety of Russian news agencies.

The object appeared to be a large metallic block, according to the reports. The researchers chipped a piece of the object and will now test its composition.

One scientist said based on his calculations, the mass of the space object headed for Earth in 1908 was nearly 1 billion tons. He believes the meteorite was blasted by the spaceship at an altitude of 10 kilometers to prevent the destruction of all humanity on the planet.

I know...I was checking for a Scrappleface URL also, but the story is also here, in the Washington Times.

The only picture currently available is this one:

Pretty blurry, but if you squint your eyes, you can almost see Bigfoot.
