The UFO controversy has always been stugguled for respectablity. Back in the early 1900's a man named Kenneth Arnold claimed to have seen a flying saucer. The media of course made him out to be a fool. He proceeded to wright a book called the Truth about UFO's, the book made it to the best seller list, but not for the wright reasons. That same year all the cheese UFO movies came out. When that article came out the UFO sightings increased more than ever before. In the sixties Projct Blue Book was the case. Project Blue Book was the Air Force's project to see if UFO's created a threat to national security. You can read more about that on the third page.
