[BLANK] radar-visual unidentified-object report — September 1966

On or during September 1966, at or near [BLANK], the source reports the following sequence: PROJECT CORONA HARVEST DO NOT DESTROY 4900 Test Drive (AFSD) UFO Material 19 Sep 66 - 25 Oct 66 SWSS-2 Unidentified Flying Object Report, Project Grudge Mr. The letter discusses a report of an unidentified flying object that was made on or about December 27, 1949. 93703 Attention: Commanding Officer Dear Sir: On or about December 27, 1949, the Air Force made a report dealing exclusively with unidentified flying objects. Condon - head of the University of Colorado Investigative Program - opened the session with a brief introduction to the UFO's: (1) The first reported sighting was at Mt. Low followed Dr. Low stated other studies include: (a) Human perception. (b) Press coverage. (Is there an inter-correlation between press coverage and the sightings?) (c) Optical mirage problems. (Refraction/similiar effects). (d) Instrumentation. (Is present instrumentation personnel sufficient, i.e., radar, FAA, weather observers, etc.). (e) To what extent do the reports of UFO's reflect the culture of the times. (f) Radioactive charged gasses emitted from the earth's surface. (g) The production of valid photographic evidence. (h) Possible conspiracy. (Yes or no? Roach, astronomer, followed Dr. Low with the statistics: (1) This graph represents the total sightings, by year, 1947: (2) A breakdown on those sightings follows: Between 1947 and 1965, the mean unidentified sightings represented 80% of the total, however, nearly 20% were unidentified because of "insufficient data". (3) A breakdown of those identified between 1953 and 1965: Those which are astronomical were not reported by qualified astronomers: Meteors - - - - - 1,295 Stars, planets - - - 805 Other - - - - - - 67 Total - - - - - 2,167 The miscellaneous sightings include missiles, hoaxes, flares, mirages, searchlights, chaff, birds, satellite decay, radar anomalies, reflections, clouds and contrails, etc. He discussed the following: (1) Dust on the cornea of the eye. (2) Pressure, either external by the fingers or internally means, can cause unusual visual images. (3) After-images from staring at a light source. (4) Auto kinetics. (5) Apparent size of image or after-image. (This varies with distance, that is to say, the various sizes can appear the same with varying distances.) (6) Distortions and illusions. (7) Gamma movement. (A slight the size of a searchlight may go out or disappear when turned off, but reappear to fade away). (8) Personnel error in estimation of celestial angles is consistently wrong when near zero degrees or ninety degrees. (9) Persons who read about UFO's are more likely to (10) Non-scientific personalities are more likely to (11) "Paranormal explanation" very unreliable. (12) Photos. (Hoaxes and defects in developing, i.e. and refraction of light source). Rush followed with examination of the instrumentation required for the conducting of UFO investigations. And last, but not least, we were instructed to keep "open minds." Since we are now in the age of space travel, we must realize that what space travel lies just ahead, it is within the realm of possibility. (Did I tell you about the individual who came into office last week and wanted to know how to build a flying saucer?) C.
