Reconstructing the Chelyabinsk meteor’s path, with Google Earth, YouTube, and math

Stefan Geens: "Like many others, I was absolutely astounded by the meteor strike over Chelyabinsk when I woke on Friday morning. One silver lining to our self-surveilling society is that an event of this magnitude is certain to get caught on the myriad of always-on dash- and webcams. I for one could not get enough of the videos. Might it be possible to use this viral footage with Google Earth to have an initial go at mapping the meteorite’s trajectory?" tl;dr: Yes, it might.
