    The BBC have the wrong headline since they have meteor strike whereas it seems to be the shockwave of the meteor hitting the atmosphere at high speed which caused all the damage.

    Russia Today reports that at least one fragment of the meteor hit a zinc factory and damaged the city of Chelyabinsk's telecoms network. But Russia Today does have a tendency of making things up, and that same report suggests that the Russian military shot down the meteor, which is preposterous.

    Either way, there's some absolutely incredible footage.

    The Guardian has a live feed with updates: http://www.guardian.co.uk/science/2013/feb/15/meteorite-explodes-over-russian-urals-live-updates

    The whole thing reminds me way too much of "Armageddon" where they "predicted" a meteorite swarm foretelling the arrival of the big one. Did Bruckheimer consult with specialists?

    Of course, there's no connection to tonight's close passing of the big asteroid all the scientists say, it's a collossal coincidence of astronomic proportions...something like that if you want to believe it.

    In that last video, and several others I've seen online, the sound of that meteor is really interesting. Following the initial sonic boom, you can hear several other pops/booms that I assume are other pressure waves from the tumbling meteor.

    Those video's are pretty chilling. Definitely cream the pants time if I was around there.

    I just love how the Russian drivers seem to take the flaming ball of doom in stride. They don't even seem to swerve or slow down to look at the bright, blinding, light consuming everything around them.

    Aside from atmospheric compression in low Earth altitude, there WAS in fact some debris that hit the Earth from this meteorite.

    The estimated size of the object, prior to entering Earth’s atmosphere, has been revised upward from 49 feet (15 meters) to 55 feet (17 meters), and its estimated mass has increased from 7,000 to 10,000 tons. Also, the estimate for energy released during the event has increased by 30 kilotons to nearly 500 kilotons of energy released. These new estimates were generated using new data that had been collected by five additional infrasound stations located around the world – the first recording the event being in Alaska, over 6,500 kilometers away from Chelyabinsk. The infrasound data indicates that the event, from atmospheric entry to the meteor’s airborne disintegration took 32.5 seconds:
