Here's a collection of insane videos of the event, some with the enormous sonic boom:

Can anyone translate what they are saying in the first one?

You can get a good idea of the new videos being posted using YouTube's "last hour" filter:

The explosion is clearly audible 25 seconds in to this clip: http://www.youtube.com/watch?v=Np_mpGYSBSA

Great video except for the Vertical Video Syndrome [1]. Is that glass breaking right after the shockwave? I wonder what kind of overpressure it generated.

eta: ghshephard posted a link to a better video with the clear sound of glass breaking. https://news.ycombinator.com/item?id=5224858

In the first video, it's mostly "WTF" and "we are being bombed", or "military testing" - in the beginning

... followed by a more scientific discussion, about it being a meteorite breaking up etc

>According to unconfirmed reports, the meteorite was intercepted by an air defense unit Anyone else catch this? Is this just a bad translation and they mean to say that an air defense unit tracked the meteorite on radar? I wouldn't think any air defense system would be capable of actually intercepting a meteorite, but perhaps I'm wrong. Still doesn't seem like anything intercepted it from the videos.

that's BS. Even S-300 or S-400 are unable to catch such a high-speed meteorite. And we don't have anything better than those.

It seems remotely possible.

The short range missile in the S-400 can reach mach 12 and at least one source [1] seems to indicate that a meteorite at 15-20km altitude would be traveling 4500-9000mph (roughly mach 6-12) and of course they wouldn't be likely to be in a complete 'chasing' orientation.

I also wouldn't think a meteorite would be that hard to track with radar once you have an initial direction on it, depending on its composition.

Not much to translate: "WTF??? What happened? It is f*cking WAR!", "Did you see that? Did they launch a rocket? Looks like they did... WTF!", "Shiiii... was it bomb?"

Two more good videos (high quality, trail/train detail, booms, etc):

Earlier quoted context omitted.

Does everyone in Russia have a dashcam or something? It seems like every other video I see on YouTube was recorded on one, and yet I don't know of anyone in Japan or the US with one installed (parking cams don't count). It's a great idea– I would probably get one if I still had a car, but it's amazing to me just how prevalent they seem in Russia. (Elsewhere too? I don't know. I'd love it if someone could enlighten me…

Yes apparently to avoid people jumping infront of car and suing the driver: http://www.animalnewyork.com/2012/russian-dashcam/

Awesome! I hope those catch on in China also for the same reason.

It takes events like this to highlight how awesome it is to have a large number of people constantly recording video. Integrated dashcams with a circular buffer should become ubiquitous standard equipment IMO. 1080p of first clip available on YouTube: https://www.youtube.com/watch?v=7c-0iwBEswE

Police corruption, scams of all kinds including from organised crime and even pedestrians, auto-insurance extremely expensive without dash cams due to high claim history, poor road maintenance especially in winter conditions leading to higher volume of accidents, courts intolerant of any evidence other than video due to unreliability, etc.
