Here's a collection of insane videos of the event, some with the enormous sonic boom: http://www.youtube.com/watch?v=XIAm5hq8WWc http://www.youtube.com/watch?v=b0cRHsApzt8 http://www.youtube.com/watch?v=Np_mpGYSBSA 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: http://www.youtube.com/results?search_query=%D0%BC%D0%…

A bunch of videos around town and some photos of damage etc.

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

Maybe I've lived a sheltered life, but I've been watching that video over and over again.. It's like nothing I've ever seen before and I'm having a hard time believing it is real.

Just amazing. I love the technology we live with.

I don't understand the language but I hear lots of "yeah boy" in these videos. They seem less concerned than I'd imagine myself to be.

Edit: haha, thanks for the explanations; that changes my interpretation of their reactions.

>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.

A meteorite would be hypersonic when first entering the atomsphere and then supersonic the rest of the way until maybe a few hundred meters before impact. Besides that, if it's not a solid iron-nickle meteorite, it may even breakup or explode well above the surface instead of staying intact. It's not quite like taking out a satellite in low Earth orbit in that there's plenty of information on its orbit, trajectory, t…

I don't know about "taking it out" per se but an air defense system designed to hit ballistic missiles in the terminal phase could also hit an inbound meteorite. It is within the performance envelope of those types of systems. That said, against a meteorite it won't do much good since it is an inert mass.

It is plausible that the Russians launched an interceptor just to be safe. If it is a meteor, it neither hurts nor helps. If it is a man-made structure, it will do some real damage to it. Either way they can always argue "better safe than sorry".

I don't get why everyone seems to be running out of (what appear to be) fairly sturdy concrete buildings and into the street. Sure, a building won't protect you from an incoming meteorite of any size, but being indoors might protect from fragments if an incoming meteor hits something else.

...provided you know it is a meteorite attack. Apparently, no one did.

They are basically cursing.
