Summary

In July 1949, a witness in Yellowstone National Park reported seeing eight aerial objects that appeared to be bright, round discs about 20 feet in diameter. The observer, along with his wife, was fishing on Shoshone Lake when they heard a sound resembling duck wings. Looking up, they saw the objects at an estimated altitude of 800 to 1100 feet, moving without formation and without visible exhaust. The report concluded that the objects were birds, possibly due to sunlight reflecting off their wet bodies. Despite the detailed description, there were no photos or physical evidence. The witness insisted the objects moved with a speed and precision that seemed unnatural.

The report is part of a U.S. Army project that analyzed over 375 UFO sightings. The official conclusion was that these phenomena could be explained by optical illusions, birds in flight, or even hoaxes. However, the witness insisted what he saw was real and not explained by natural causes. His testimony, though unverified, reflects the confusion and mystery surrounding UFO reports at that time. The document includes a letter from the Air Force responding to the report, assuring that the information provided would be considered.
