about them, and how those conclusions were reached. If we had identified a UFO, the audience was told how the identification was made. If we concluded that the answer to a UFO sighting was "Unknown," the audience learned why we were convinced it was unknown.
Among the better sightings that were described fully to interested government groups were: the complete story of the Lubbock Lights, including the possible sighting of the same V-shaped light formations at other locations on the same night; the story of a group of scientists who detected mysterious nuclear radiation when UFO's were sighted; and all of the facts behind such famous cases as the Mantell Incident, the Florida scoutmaster who was burned by a "flying saucer," and headline- capturing sightings at Washington, D.C.
I showed them what few photographs we had, the majority of which everyone has seen, since they have been widely published in magazines and newspapers. Our collection of photographs was always a disappointment as far as positive proof was concerned because, in a sense, if you've seen one you've seen them all. We had no clear pictures of a saucer, just an assortment of blurs, blotches, and streaks of light.
The briefings included a description of how Project Blue Book operated and a survey of the results of the many studies that were made of the mass of UFO data we had collected.
Also covered were our interviews with a dozen North American astronomers, the story of the unexplained green fireballs of New Mexico, and an account of how a committee of six distinguished United States scientists spent many hours attempting to answer the question, "Are the UFO's from outer space?"
Unfortunately the general public was never able to hear these briefings. For a long time, contrary to present thinking in military circles, I have believed that the public also is entitled to know the details of what was covered in these briefings (less, of course, the few items pertaining to radar that were classified " Secret," and the names of certain people). But withholding these will not alter the facts in any way.
A lot has already been written on the subject of UFO's, but none of it presents the true, complete story. Previous forays into the UFO field have been based on inadequate information and have been warped to fit the personal biases of the individual writers. Well meaning though these authors may be, the degree to which their books have misinformed the public is incalculable.
It is high time that we let the people know.
The following chapters present the true and complete UFO story, based on what I learned about UFO's while I was chief of Project Blue Book, the Air
Force's project for the investigation and analysis of UFO reports. Here is the same information that I gave to Secretary of the Air Force, Thomas K. Finletter, to the Air Force commanders, to scientists and industrialists. This is what the Air Force knows about unidentified flying objects.
You may not agree with some of the official ideas or conclusions -- neither did a lot of people I briefed -- but this is the story.


The 34th Air Defense Division at Albuquerque New Mexico was the base that Ruppelt used to visit frequently because of good UFO reports. From 1951 to 1960, the 34th Division's area of responsibility included Arizona, New Mexico, and parts of Nevada, Utah, Colorado, and Texas.

Lieutennant Glen Parrish was the Intelligence Officer who passed some of the best reports on to Ruppelt and was the one who showed him the F-86 shooting report. Parrish was conservative with respect to his belief in UFOs, but he did take them seriously enough to warrant careful investigation. Colonel Methany, on the other hand, was the Commanding Officer of the 34th Division and a proponent of the ETH.
