Son of a bolide
bitch. 
Thanks for the post, PP. Somebody up there has it in for Russia; first Tunguska (
http://en.wikipedia.org/wiki/Tunguska_event) and now this, just over a century later. Ai karai. I guess it helps when you have the biggest land surface in the Northern Hemisphere, but wow. Just wow.
As if life wasn't interesting enough there already. And aren't the tin-foil-hat brigades gonna have a fine time with this, with the Earth-crosser 2012 DA14 making a close pass later today.
The Bad Astronomer has an initial post:
http://www.slate.com/content/slate/blogs/bad_astronomy.html He points out (no doubt futilely to some) that this object is likely completely unrelated to DA14; for it to intercept Earth so many hours ahead means it was in a completely different orbit.
I guess we can thank the insurance companies of the Russian Federation for some of that footage, since it's because of their reluctance to pay up that drivers started installing dash cams in everything that has an engine. Sure hope no one was seriously hurt; the BA is saying windows (unsurprisingly) shattered in a lot of places.
