Living in America, UFOs seem like an American preoccupation.  It was interesting to see (non-serious) news regarding British UFOs although strangely the American military still seems to be the primary source regarding experimental flights and air-born equipment. Without taking it too seriously I have heard people dismiss UFO sightings because they have never heard of them outside of the United States.  It turns out that based on collected reports and mapping, it’s pretty much a global phenomenon and happens more in cities than the country despite the frequent ditching of flying saucers/weather balloons in remote fields. 

So are they from outer space or an0ther universal human experience like mothers that tell their children to wear clean underwear in case they have to go to the hospital?  (The last has been personally verified for seven different countries on all the occupied continents.)
