Hello guys! I live here (in Chelyabinsk) and I saw it with my eyes. That WAS scary! :-)

Did you hear the boom?

"Hear" is not the word. It was like earthquake for those seconds. I can write a sum-up of what I saw and heard a bit later. We just woke up because of hard morning! :-)

Given the time delay in the sonic boom, the speed of sound etc. that puts this contrail several miles up. That's one hell of a big contrail if that's the case!!!

We think the same. Sonic boom was 2 min 30 sec later after we saw it. Plenty of time...
Interesting why that happening? Does military not fire them with missiles? (to change its trajectory) Why this not happened before? (I mean past 50 years) And whats with the big one today?

It was likely too small to detect. When you don't know it's coming, hard to be prepared to shoot anything down.

Its not that late, if it takes 30 seconds for the sonic boom to arrive, -speed of sound is approx 335 m/s (depending on altitude, air moisture and air temperature)- it means that the asteroid was just flying by at ~ 10.000 meters altitude.
Still, a lot of sound traveled that far.
Oh, and the reason why pretty much all Russians cars have dashcams installed is to record evidence in case of police brutality. Which is a big problem in Russia.

This might be off topic here, but there is a big asteroid circling us now. Should be closer than our satellites?
Yes, it's ~50 meters in diameter and has no chance of hitting in your, currently average, lifetime. It's called 2012 DA14.
It has a 0.00000021% risk (1 in 4,700,000), chance of hitting between 2080 and 2111.
These types of asteroids (DA14, not this small one that hit Russia) impact every 1200 years or so.
Even if it were to impact Earth it was calculated it would have a kinetic energy equivalent to 3.5 megatons of TNT. The Tunguska event has been estimated at 8 to 20 megatons. Impacts like those are "city-killers" but when they do hit there's much more chance of it hitting water or wilderness than us having really bad luck and having a big city hit right on.
So it would be pretty devastating, but not like Tunguska, which did this:

- Agremont
Scary.

I hate when that happens. Makes it hard to pee.
I didn't see anything that struck me as an intercepting missile, and of course you guys have a history of massive asteroid impacts.
Sounds like an insane thing to wake up to. I guess enjoy the fact that it wasn't worse, because a little bigger and that thing might have really taken a toll.

While I agree that it's quite fascinating to be a witness of this (even just through videos), a lot of people got injured, some of them might have lost an eye, or more.
Jebus, good that no one was there at this time.

To all the folks saying, "Hey, they shot it with a missile," or "Why can't they shoot it with a missile?" and other such nonsense.
First, you have to know it's there. Not only that it's there, but exactly where it's going. An EXACT predicted path. Something as small as this thing was would never have been tracked in space. There was no military reaction, because they knew about it the same time as everybody else; after it went by at 647 quajillion miles an hour.
Second, even if a missile were able to intercept it, it would not be "destroyed" The mass of the object wouldn't simply disappear from our Universe. If it was 860 tons of rock, then it's still 860 tons of rock after being blasted to smithereens. And smithereens is fairly relative; there will still be BIG chunks of rock falling down.

Unconfirmed reports of another one that entered over Cuba. Obviously video of that one may be harder to come by...
