At first, I thought it was a movie. They had a lot of disaster movies playing that day, so I didn't think anything of it until I started channel surfing and noticed it was on damn near every channel. That's when I realized it wasn't a joke. I can remember thinking that this was the start of the path to WWIII then shortly after, Zephram Cochrane will invent warp drive and Star Trek will be born! :D (Yes, I seriously thought that a week after the shock lapsed)
