There is an unusual dichotomy about UFO research. On the one hand, we are told there is nothing of value to it by the military and intelligence agencies. Yet, these very same agencies tend to be the one's who expend the greatest time, effort, and resources to keep control of the investigations and release of any results. The discrepancy lies between the interest shown by the intelligence community that infiltrates civilian UFO groups and the mainstream scientific community that has traditionally ignored the situation entirely.

A newcomer to the study will find their quest for knowledge waylaid at every turn. Even established scientists have continuously failed to get proper research and disclosure done through the "mainstream" routes of research. The theories behind UFO phenomena also gravitate toward a schism of thought. There are the more fantastical ideas of Shaeffer and Klass to set a counterpoint to the more conservative scientifically oriented outlook of Ruppelt, Kynek, or Keyhoe. Some areas of study focus on UFO's more in the paranormal realm than the practical science. With the squirreling away of any real knowledge by the military and intelligence agencies that are in the best position to have figured out the truth, a new researcher can have no clear path to follow.
The "great wave" of UFO sightings in the 20th Century started with the "foo fighters" of WWII and continued after the war with American observations of what were called "ghost rockets" over Europe in 1946. While they were studied by the Greek military and determined not to be either Russian or "rockets," the United States military did succeed in slapping a label of secrecy over the results. Then 1947 saw the massive outbreak of sightings all across the United States itself.
While the military agencies managed to keep the vast majority of these events secret from the public, they were often of very major and potentially catastrophic events. Many of these unknown craft were violating restricted air space over nuclear and top secret test facilities. As well as many military bases, the airspace over the Oak Ridge Nuclear Facility, Los Alamos, and Hanford were repeatedly trespassed upon. Even General Nathan Twining had noted in a classified memo that "some of the objects are controlled." He never hazarded a guess as to "what" controlled them.
By 1949 a confidential FBI internal memo was passed around stating "Army intelligence has recently said that the matter of "unidentified aircraft" or "unidentified aerial phenomena" ... is considered top secret by intelligence officers of both the Army and the Air Forces." A year later, Department of Defense Research and Development Board physicist Robert Sarbacher confided to the Canadian official Wilbert Smith that "UFO's are the most highly classified subject in the U.S. government."
Obviously the military and intelligence community feels they know enough about the UFO phenomena to make sure the public never learns the truth. It was a combined effort by the CIA and Air Force Intelligence that began the campaign in 1952 of ridiculing anyone who reported seeing a UFO. In the mid 1980's even such a trusted UFO researcher as William Moore finally confessed to having been part and parcel to a massive misinformation campaign to refute and confuse real civilian research on UFO's. Many people in the top echelons of the civilian UFO research organizations have had and still have past connections to the various covert intelligence agencies.
The clearest fact to be discovered concerning the UFO phenomena is that a great deal of effort is made at the highest levels to keep the average person from ever knowing the truth. A study of human nature will show that such activity is almost invariably done to maintain control over other people. What dirty secrets are constantly being hidden behind "national security" that would so require them to be kept for so long behind their "classified" covers?
