Stuff will definitely be recovered, I think at least one fragment has been reported already. A meteor this size in an area this populated is probably a once-per-century or more kind of event. It's also been reported that 100+ people have been injured.

Meteors of this size fall to earth yearly or so, but usually in little populated areas, and quite rarely will they cause widespread damage. This kind of damage might be a once in a decade event or less globally. It's not the first time in recent years that such sonic booms break windows, but for this event the damage seems quite widespread.

It's certainly going to be the best documented meteor explosion so far.

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.

Broken windows video (make sure your speakers is not very loud):

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. smile

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. biggrin

Amazing photos from airplane:





The text says "This is the explosion place and it is certainly higher than our echelon (10400 m)"

One of the Belgian newscasts used the picture of that burning gashole as if it was the meteor crater, bad bad bad TV-makers, check your sources!
