Uh, hi! Some weeks ago I catched a documentary on Discovery that was mainly about what would happen if something big hit Earth. I was wondering what was the name of it, if anyone knew. It was unlike the others of the same theme, because everything was detailed - how the people ran and hid, how everyone was evacuated and then the big thing hit earth, everything was shown and after that they even showed what would happen after the impact, how all the cities would be destroyed, etc. I searched for it, but I only found somethings that showed how the Earth would recieve the impact, but none was so detailed. So I was wondering if someone knew the name of the documentary or whatever it was?
