Muroc Officers and Portland Police Report Discs, 1947

DOW-UAP-D087, U.S. Air Force Analysis of Flying Objects in the United States, 1-100

This file is a Secret Department of War collection of 1947 unidentified flying object checklists, witness statements, and short evaluations from U.S. locations including Muroc Army Air Field, Portland, Vancouver, and Ohio.

Brief

The provided pages show a case packet built from standardized unidentified flying object checklists and narrative witness reports. Several reports describe silver or aluminum disc-like objects, no sound, no exhaust trails, high speed, and sharp or circular maneuvers. The strongest early cluster comes from Muroc Army Air Field on July 7, 1947, where multiple military and civilian witnesses reported disc-like objects near Mojave, California, and one entry was evaluated as confirmed by other sources. Portland police reports from July 4, 1947 add corroborated accounts from officers who were also private pilots.

Key points

The file uses a repeated 'Check-List - Unidentified Flying Objects' format that records date, time, observer, occupation, location, number of objects, speed, altitude, shape, color, trails, weather, sketches, and remarks.p.7
Muroc Army Air Field witnesses reported three objects on July 7, 1947, first two objects and then a third, with the third making a tight circle.p.7
One Muroc witness described two silver-colored disc-like objects flying toward Mojave at about 300 to 400 MPH and about 8,000 feet, followed by another similar object making a tight circle.p.11
The Muroc account on page 11 was evaluated as confirmed by other sources.p.11
Major J. C. Wise, identified as a test pilot at Muroc Army Air Field, reported on July 7, 1947 that he saw an object north of the field that he first assumed was a weather balloon.p.16
Portland patrolman Sergeant Claude Cross reported three discs moving northwest at terrific speed, with a whitish brown glint and no sound.p.22
A Portland witness reported one aluminum-colored disc at an estimated altitude of about 30,000 feet that changed direction at a 90 degree angle without difficulty.p.24
Portland patrolmen W. A. Lissy and D. W. Ellis, both noted as private pilots, gave mutually corroborating accounts of three flat round discs with no visible propulsion, no vapor or smoke trails, and no sound.p.26
A Vancouver-area photographic report says Rycan and his wife watched a shiny ball at great height for about 10 minutes, but the page is partly illegible.p.37

Verbatim

Witness states that she saw 2 silver-colored disc-like objects flying toward Mojave, Calif, one directly back of the other, at a speed of about 300 to 400 MPH at an altitude of approximately 8,000 ft.
p.11
Nor could they have been birds since they reflected the sun's rays.

Evaluation: Confirmed by other sources
p.11
Cross saw three discs following each other at an undetermined altitude at terrific speed, traveling in a Northwesterly direction.

No sound was made by the objects.

Witness was getting out of his car when he observed one disc flying in a Southwesterly direction over Portland.

Most interesting

The Muroc cluster includes military office personnel, enlisted witnesses, a secretary, and a test pilot, not a single isolated observer.
Several Portland entries identify police officers as private pilots, a detail the file uses to support witness reliability.
Multiple reports independently note the absence of engine noise, vapor trails, or smoke trails.
The file records both ordinary explanations considered by witnesses, including weather balloons, aircraft, and birds, and the reasons some witnesses rejected those explanations.
At least one Vancouver-related entry included a photographic effort, but the extractable page text is partly illegible.

Plane had just passed Necker Island at 0553 00Z. At 0558 00Z an intense white light was observed 60 off starboard bow of plane. It appeared similar to light of an approaching plane except that it was extremely intense. The color was that of an incandescent light although it was approximately blue and a reddish tinge. It appeared on a course about 350 true approximately 5 miles away. The light grew in intensity (but without any change in color) to a point estimated to be one mile off starboard bow of the plane. When the PA plane switched over to unusual control, the object suddenly veered to an approximate course of 109 and then the bright lights did not have the intensity of the extraordinary light. These two reddish lights did not have the intensity of the extraordinary light. As it changed its course the extraordinary speed was noted. It far surpassed the Pan American plane and the twin lights appeared to burn out 30 miles ahead. The entire phenomenon was observed for some sixty seconds. Object was estimated to be traveling 1,000 knots per hour. NOTE: Both observers thought it could have been a meteor except for the manner in which it held altitude. At no time did it appear to get above or below 9,500 ft. When it disappeared it still seemed at about 9,500 ft. at no time did it give off sufficient illumination to reflect on the [ILLEGIBLE] Both observers were questioned as to possibility of optical illusion and the probability that the object dropped at an oblique angle but both firmly declared the object generally changed course and that it appeared to hold altitude throughout the entire time observed. PAA plane was eastbound from Midway on magnetic course 92, which is approximately 110° true, and flying at 6,000 feet at about 205 knots. It was flying on automatic pilot with Griffin in the right-hand seat in the control cabin and Pollmann in the left-hand seat. It was dark and there were omitting clouds of about .4 density. The sun had set by minutes previously.
