No smoke, flames, propeller arcs, engine noise, or other plausible or visible means of propulsion were noted. The color was silver, resembling an aluminum-painted fabric, and did not appear as dense as a parachute canopy.
When the object dropped to a level such that it came into line of vision of the mountain tops, it was lost to the vision of the observers.
It is estimated that the object was in sight about 90 seconds. Of the five people sitting in the observation truck, four observed this object.
The following is our opinion about this object:
It was man-made, as evidenced by the outline and functional appearance.
Seeing this was not a hallucination or other fancies of sense.
Exactly four hours later the pilot of an F-51 was flying at 20,000 feet about 40 miles south of Muroc Air Base when he sighted a “flat object of a light-reflecting nature.” He reported that it had no vertical fin or wings. When he first saw it, the object was above him and he tried to climb up to it, but his F-51 would not climb high enough. All air bases in the area were contacted but they had no aircraft in the area.
By the end of July 1947 the UFO security lid was down tight. The few members of the press who did inquire about what the Air Force was doing got the same treatment that you would get today if you inquired about the number of thermonuclear weapons stock-piled in the U.S.’s atomic arsenal. No one, outside of a few high-ranking officers in the Pentagon, knew what the people in the barbed-wire enclosed Quonset huts that housed the Air Technical Intelligence Center were thinking or doing.
The memos and correspondence that Project Blue Book inherited from the old UFO projects told the story of the early flying saucer era. These memos and pieces of correspondence showed that the UFO situation was considered to be serious; in fact, very serious. The paper work of that period also indicated the confusion that surrounded the investigation; confusion almost to the point of panic. The brass wanted an answer, quickly, and people were taking off in all directions. Everyone’s theory was as good as the next and each person with any weight at ATIC was plugging and investigating his own theory. The ideas as to the origin of the UFO’s fell into two main categories, earthly and non-earthly. In the earthly category the Russians led, with the U.S. Navy and their XF-5-U-1, the “Flying Flapjack,” pulling a not too close second. The desire to cover all leads was graphically pointed up to be a personal handwritten note I found in a file. It was from ATIC’s chief to a civilian intelligence specialist. It said, “Are you positive that the Navy junked the XF-5- U-1 project?” The non-earthly category ran the gamut of theories, with space animals trailing interplanetary craft about the same distance the Navy was behind the Russians.
This confused speculating lasted only a few weeks. Then the investigation narrowed down to the Soviets and took off on a much more methodical course of action.
