| Quote (Salvo) if DA14 hit it would have done A LOT more damage than that.
What?! Do you think that will remain in history like Tunguska event?
It would, if it had hit the Earth. The Tunguska meteor (30-40m) was probably just a little smaller than 2012DA14 (40m).
So if 2012DA14 ever strikes (like in the far, far future) it will have a similar effect, unless it's above the ocean.

2 min 20 sec = 140 sec, even in blast wave traveled with sonic speed (330 m/s), it will be 46 km away. In reality blast wave is supersonic...

| Don't trust YouTube. That crater has nothing to do with the meteor! It's natural gas.
But this fake is a good one.

It is currently below the horizon for the northern hemisphere I think. Anyway you will need binoculars at least to see it.

No. Here in Oslo it rose above the horizon four minutes after its closest approach. But it's 100% overcast and snowing slightly. So I can't see it, but I have a long period seismometer and if it had hit earth I would have known by now.

| Amazing photos from airplane:
The text says "This is the explosion place and it is certainly higher than our echelon (10400 m)"

Yes. One other thing that's repeated in the news is that the collapsed factory was hit by a meteorite.
I've read today, and I assume that it's reliable, that divers have looked for the fragment that made the 6 meter hole in the lake outside Cheburlak. The lake was muddy and visibility was poor, so they found nothing. Meteorite fragments hit the ground in free fall, so there must be a fragment of some size that hit the lake in order to make a splash big enough to create a 6 meter hole. Certainly more than a few kg or it would only pinch a tiny hole or just embed itself in the ice. Above 100 kg, perhaps? But that will depend on what it's made of.
NASA now think that the meteor might have been as big as 10,000 tonnes, 17 meters in diameter and released half a megaton of energy. They seem to base that on infrasound detected around the world.
