The Black Vault (USAF records) · 62 pages · text by GLM-OCR

This US Air Force Project Blue Book case file on Kenneth Arnold's sighting of nine objects near Mount Rainier, Washington, on 24 June 1947 was released through The Black Vault. It contains the Project 10073 record card, which concludes the objects were a mirage, plus Arnold's telegram, questionnaire data and interview notes. It also includes J. Allen Hynek's analysis arguing the objects were closer and slower than Arnold estimated. Other items are David Johnson's sworn statement on a Boise sighting, a Tacoma investigation telegram and news clippings.

and one-half or three minutes although, by the time they reached it. Adams they were out of my range of vision for as determining shape of course, when the sun reflected from one or two or three of these units, they appeared to be completely round; but, I am making a drawing to the best of my ability, which I am including, as to the shape I observed these objects to be as they passed the snow covered ridges as well as Mt. Rainier.

When these objects were flying approximately straight and level, they were just a black thin line and when they flipped was the only time I could get a judgment as to their size.

These objects were holding an almost constant elevation; they did not seem to be going up or to be coming down, such as would be the case of rockets or artillery shells. I am convinced in my own mind that they were some type of airplane, even though they didn't conform with the many aspects of the conventional type of planes that I know.

Although these objects have been reported by many other observers throughout the United States, there have been six or seven other accounts written by some of these observers that I can truthfully say must have ob- served the same thing that I did; particularly, the descriptions of the three Western/Air Lines employees, the/gentleman from Oklahoma City and the loco- tive engineer in Illinois, plus Capt and Co-Pilot of United Air Lin

Some descriptions could not be very accurate taken from the ground unless these saucer-like disks were at quite a great height and there is a possibility that all of the people who observed peculiar objects could have seen the same thing I did; but, it would have been very difficult from the ground to observe these for more than four or five seconds, and there is always the possibility of atmospheric moisture and dust near the ground which could distort one's vision.

I have in my possession letters from all over the United States and people who profess that these objects have been observed over other portions of the
