There was a show on the History Channel about this one time and they showed various documents about what to do, but I cannot find them on the internet because if you type in the word "UFO" 10 million pages come up. I remeber one part of the show. It was talking about an UFO entering a public area. It said that the fire fighters would be the first on scene and that you shoudl not cause it harm unless it is causing you harm. The firefighters are suspossed to try to revive it if it is unconsious and if it does cause you harm you should try to keep it pinned down until the military can arrive. I know they arent the best details, but its all i remember.
