UAP Sighting Report — Phoenix, Arizona, July 1952

This document comprises a series of reports and questionnaires regarding an unidentified aerial phenomenon (UAP) sighting in Phoenix, Arizona, on July 28, 1952. The primary witness, a civilian woman, reported observing a flying-wing-shaped object, approximately the size of a B-36 bomber, passing overhead while she was on her porch with her son. The object was described as dull grey with a series of orange glowing windows on its underside. The witness noted that the object made no sound and travelled at the speed of a jet aircraft. The sighting lasted between 10 and 15 seconds. The report, filed by Captain Frederick R. Roper Jr. of the 127th Pilot Training Wing, includes sketches provided by the witnesses and an artist, Arthur Wolff, depicting the object's shape and light configuration. The official military assessment, submitted in compliance with Air Force Letter 200-5, concluded that there was no significance attached to the report, noting that the witnesses had been exposed to recent 'Flying Saucer publicity.' Despite the official dismissal, the documentation provides detailed accounts of the object's behavior, including its appearance, the lack of propulsion noise, and the specific weather conditions at the time of the sighting. The file also contains administrative correspondence, including an Air Intelligence Information Report (IR-56-52) and various iterations of the 'Tentative Observers Questionnaire' completed by the witnesses. The documentation highlights the military's systematic approach to collecting civilian reports during the 1952 wave of UAP sightings, while simultaneously maintaining a skeptical stance regarding the nature of the reported objects.
