Four documented cases from the first half of May 1952.
1952: May 1st–15th
UFO|UAP & Entity Sightings Archive
The first half of May 1952 opens the busiest stretch of the year’s UFO wave, and the witnesses are not the usual casual skywatchers: Atomic Energy Commission employees at Hanford, DuPont workers inside the Savannah River Plant, a B-36 crew in Arizona that watched two shiny discs overtake their bomber, and Air Force airmen at George AFB who reported five flat-white discs making a 90° turn over the desert. This May 1952 UFO sightings archive gathers every case from May 1 through May 15, from Project Blue Book record cards and Air Intelligence reports to the pilot, radar and press accounts that surround them.
Night after night the reports pile up: a Pan American DC-4 crew over the Atlantic, F-86 and F-51 pilots over North Korea, a deputy-sheriff chase in California’s Imperial Valley, four amateur astronomers under a diamond of glowing ovals in South Carolina, and a British scientist watching a luminous disc climb from the sea off Cyprus. Blue Book later explained many of them as meteors, balloons and aircraft, and those evaluations are recorded here beside each case, but a stubborn core of reports was left unidentified. Because of the volume, May is split into two archive pages; this page covers May 1st–15th, and the companion page covers May 16th–31st.
Date: May 1952 (day unknown; date doubtful)
Location: Allyn (or “Allen”), West Virginia
Time: 8:00 p.m.
Summary: A woman driving at night was paced by an object with many lights; her car slowed to a stop, and she found herself aboard a craft where small grey beings with large eyes examined her and something was placed behind her ear. She reported about three hours of missing time. [Full Report]
Source: NUFORC report
Source Status: Anonymous, unvalidated submission to NUFORC, a hotline founded in 1974; the account’s features postdate 1952, so the date is doubtful. Provisional Hynek CE-IV; Insufficient Data.
Date: May 1952 (day unknown)
Location: Prospect Heights, Cook County, Illinois
Time: 10:50 p.m.
Summary: Mrs. Ann Sohn saw a white luminous disc with a row of square windows, a transparent dome on top and green glowing vapor beneath hover over a vacant lot beside her home. Through the lit windows, three men in hooded, parka-like coveralls appeared to work mechanical levers for three to five minutes; the disc then turned brilliant red-orange and left at “fantastic speed.” [Full Report]

Source Status: Single witness; summary report only, with no interview transcript or field notes; Insufficient Data. Provisional Hynek CE-III.
Date: Early May 1952
Location: Willow Grove, Pennsylvania (Naval Air Station)
Time: Unknown
Summary: A Naval Air Station ground-controlled-approach radar tracked a target in bad weather moving at roughly 3,600 mph. The target appeared on two scopes operating at different frequencies and was tracked again the following day.

Source Status: No Blue Book file in the May 1952 set; the exact date within early May is not given in the source.
Date: May 1, 1952
Location: Moses Lake, Washington (Hanford area)
Time: 5:32 a.m. PST
Summary: Civilian AEC employees at the Hanford area saw a slow-moving, wingless silver object flying straight and level at about 5,000 feet for roughly 1½ minutes. Blue Book noted that a Yakima balloon release at 1:15 a.m. PST was considered doubtful as an explanation and recorded no conclusion.

Date: May 1, 1952
Location: Davis-Monthan AFB, Tucson, Arizona
Time: 9:10 a.m. MST
Summary: Two shiny, round metallic discs, the nearer lens- or double-disc-shaped and about 20 to 28 feet across, overtook a westbound B-36 at about 20,000 feet, matched its speed, paced it, made a sharp turn and vanished by shrinking away. Base Air Intelligence Officer Maj. Rudolph Pestalozzi, M/Sgt. Edmond L. Bouton Jr. on the base hospital steps, the B-36 crew and others saw them. According to James E. McDonald’s 1966 letter to Blue Book, every crewman but the pilot reached the starboard blister to look, the nearer disc sat below the fuselage mid-section, and the bomber demanded immediate permission to land. Estimates of how long the discs paced the bomber range from about 20 seconds to several minutes. Blue Book’s record card lists Possibly Aircraft, commenting “Might have been fighters however description precludes this.” [Full Report]

Source Status: The original report went missing from Blue Book and was reconstructed in 1966 from McDonald’s interviews; the exact date remained uncertain. Sparks catalogs the case as a Blue Book Unknown although the record card reads Possibly Aircraft.
Date: May 1, 1952
Location: George AFB and Apple Valley, California
Time: 10:50 a.m. PDT
Summary: Three men on the arms range, plus Lt. Col. Lyle Albert Silvernail four miles away in Apple Valley, saw five flat-white discs, three in front and two behind, flying at roughly 1,000 mph at about 4,000 feet and making a 90° turn before the rear pair darted in circles and zig-zags. Silvernail reported the sighting and was told radar was tracking the object(s) and fighters were being scrambled. Blue Book filed it as “well documented,” with no conclusion. Duration was 15–30 seconds, with five or more witnesses. This was the first of nine George AFB reports in three weeks. [Full Report]

Location: Barra da Tijuca, Rio de Janeiro, Brazil
Time: 4:30 p.m.
Summary: Reporter João Martins and press photographer Ed Keffel of O Cruzeiro magazine photographed a metallic or whitish disc, five exposures in about a minute, published in the May 24, 1952 issue. A Brazilian Air Force investigation, released in 1959, called the photographs genuine, and APRO ranked them among the best on record, but skeptics including Menzel, Boyd and Hartmann cite inconsistent shadows. Blue Book’s record card evaluated the case Other: possible hoax, noting that the shadows do not match the trees, that the pictures were “too easy to fake,” and an original asking price of $25,000 later changed to free use for a credit line.

EXECUTIVE SUMMARY
Nuclear Plants, a B-36 Escort, and the George AFB Cluster
The first fortnight of May 1952 is defined by who was looking up. AEC employees at Hanford and DuPont workers at the Savannah River Plant, an Air Force intelligence officer and a B-36 crew at Davis-Monthan, and a run of airmen at George AFB all filed reports, and Blue Book itself later noted that the 1 May George AFB sighting began a series of nine reports there in three weeks, all by military personnel. On May 8, Secretary of the Air Force Finletter sat through an hour-long Blue Book briefing in Washington, while the cases piled in from Korea, the Atlantic, Cyprus and the American Southwest.
Blue Book’s own record cards sort the half-month into three groups: a long list of meteors, balloons and aircraft, a handful of reports with no data to judge, and a small unidentified core that includes the Mayagüez spheres, the Keesler cylinder, the Moses Lake silver object and the five-disc George AFB report. Several cases the file explains and several it does not still rest on credible, trained witnesses, which is why this half of May is worth reading case by case.
“It appeared to disappear very fast, almost like a light being turned off.”
— T-6G observer, George AFB, California, May 13, 1952
