This CIA document from 1957 refers to photographs of an unidentified flying object (UFO) captured in 1952 by a witness named Mayher. The UFO was described as a saucer-shaped object, observed for three minutes and appearing in a bright orange color. The images were taken with a 16 mm camera, at 24 frames per second and with a lens aperture of f:2.7. Multiple copies and enlargements of the original images were made, including a large-scale version that allowed for a closer analysis of the object's shape, which seemed to flatten as its speed increased.
The document also includes technical details about the image processing, from the initial copies to 8x10 inch negatives. The witness offered to lend the negatives for two weeks if they were deemed useful for further investigation. The estimated altitude of the UFO was 2000 feet, and the maximum camera angle was 45 degrees, according to the report. Despite OCR errors in the text, the technical and visual details are clear and suggest a serious and well-documented observation.
