UNIDENTIFIED FLYING OBJECTS

    Since man first started looking up into the skies he saw things he couldn't explain. For the last fifty years or so these things have taken on the label "UFOs." Originally an abbreviation for the Air Force term "Unidentified Flying Object", it has become a synonym to most people for "Alien Spaceship." For the Air Force, though, it is simply a term to refer to something in the skies that the observer can see but not recognize. Usually the explanation is less extraordinary than a flying saucer manned by visitors from other worlds. Often a weather balloon or natural phenomenon is the cause. However, there are cases on record where no good common explanation was ever found.
