PHOENIX, ARIZONAJuly 1952

On the evening of July 28, 1952, a civilian woman in Phoenix, Arizona saw an unusual object in the sky. According to her witness statement, the object resembled a flying wing and was colored dull grey with a series of orange glowing windows along its bottom. She watched the object for approximately 20 to 54 seconds as it traveled from southwest to northeast at a high speed. No sound or means of propulsion were visible. She was certain about what she saw and described the object as solid in appearance.

A second observer, also a civilian, watched a similar object on the same evening at 2448 hours (12:48 a.m.) on July 23, 1952. This witness observed the object for 10 to 15 seconds from a ground position in central Phoenix. Both witnesses indicated they were aware of recent flying saucer publicity but stated they were sure and real in their descriptions.

The Air Force investigation included weather data from the area. At 2038 hours on July 29, conditions showed overcast skies at 1,800 feet, visibility of 15 miles or better, temperature of 88 degrees, dewpoint of 63 degrees, and south winds at 15 knots. The case file notes that three scheduled airliners landed at Phoenix's Sky Harbor Airport around 2430 hours that same evening, including one DC-3 and two Constellations.

An Air Force intelligence officer from Luke Air Base completed the official report, finding no explanation for the sightings. The investigating officer noted that both witnesses appeared familiar with aircraft and stated the observed object did not match known aircraft characteristics. No physical evidence, photographs, or other corroborating data were collected. The Air Force assigned this case the evaluation of unidentified, with no significance attached to the individual reports.
