30th Air Division History, 1951: Unusual Flying Objects Over the Midwest

What this record is

This is the quarterly history of the 30th Air Division (Defense) for October to December 1951, submitted to Eastern Air Defense Force under the name of the vice commander, Col Barry A. Branch. In 1951 the division ran radar stations, aircraft control and warning squadrons, fighter-interceptor squadrons and Ground Observer Corps filter centres across Michigan, the Great Lakes and east Tennessee, from its headquarters at Selfridge AFB. The file was classified SECRET.

The PDF has 85 pages and comes from microfilm, as the catalog warns: “some pages unreadable”. The typescript is so faint that machine text recognition picked up almost nothing, and a keyword scan found no UFO terms at all. The page images are readable by eye, though. Most of the history deals with organization and air defense. Pages 3 to 6 of the PDF cover a reorganization of air defense units and a planned move of the division, and page 20 covers better identification of flights at a radar site after new telephone lines to Detroit and Toronto were installed. Pages 48 to 85 are statistical tables of tracks plotted, tracks identified, interceptions, exercise results and Ground Observer Corps posts.

What it says about UFOs

The UFO content is on two pages, 34 and 35 of the PDF (typed pages 31 and 32), in the intelligence part of the history. It begins at the foot of page 33 under the heading “Intelligence Reporting Procedure”. This explains that work had begun on a standing procedure for a uniform way of reporting unusual radar objects, unusual flying objects, sabotage and simulated or actual hostile aircraft, to be followed by all subordinate units.

A section headed “Unusual Flying Objects” follows on page 34. It describes five reports.

The first came from near Battle Creek, Michigan, and the history gives no date for it. A civilian pilot with fourteen years’ flying experience met a “disk like, highly polished flying object” that closed head-on with his aircraft at an extremely high speed. The division’s investigation estimated the object’s altitude at 3,000 feet, 1,000 feet below the pilot, and found the pilot “a very stable individual”. Civil and military sources showed no known aircraft nearby. A report went to Air Materiel Command, Air Defense Command and Eastern Air Defense Force.

The second came in November. Six observers at five points in lower Michigan saw an object on the 24th, around 2320Z. They agreed that it moved as fast as a jet or faster, but called it round, football-shaped, egg-shaped and bullet-shaped, and gave its colour as bright white, greyish white and brilliant bluish white.

The third was two days later. On 26 November a Capital Airlines pilot 25 miles east of Milwaukee saw what he called a ball of fire, orange, with a blue exhaust-like flame behind it. A second Capital Airlines pilot, about 75 miles south of the first, apparently saw the same thing. He noticed the blue flame but not the orange object in front of it. Reports on these incidents went to AMC, ADC and EADF through technical intelligence channels.

The fourth was at Oak Ridge. On 7 December 1951, shortly after 0800 Eastern time, a civilian guard at Oak Ridge, Tennessee, reported an airborne object travelling at about the speed of an ordinary aircraft. He described it as square, roughly 20 feet wide, grey-white, with no markings. The history notes that he was 49, honest and conscientious, and highly respected by his employer. “Two F-47’s were unsuccessful in an attempt at interception.”

The fifth came from Hamden, Ohio, where a civilian reported watching a large round light for nearly three hours early on the morning of 22 December 1951. A follow-up phone call produced the names of corroborating witnesses, and the report went to EADF.

An enhanced re-reading of all 85 page images found no other UFO passage. The scan is faint, though, so a brief passing mention elsewhere can’t be ruled out.

Context

In late 1951 the Air Force’s UFO project, Grudge, was being revived at Wright-Patterson under Lt Edward Ruppelt. It became Project Blue Book in March 1952. Air defense divisions like this one were building their own reporting rules at the same time, and the draft procedure in this history is an early version of what became standard. The site’s page on the 1950 volume of the same division’s history covers an earlier Oak Ridge report, and the summer 1952 wave shows where this rising volume of reports led.

Status

This record adds a first-hand air defense summary of five late-1951 reports, with the actions taken on each. It also shows the division taking pilots and guards seriously and vouching for their reliability. It gives no explanations and no radar data. The failed interception at Oak Ridge is the most concrete detail, but it proves only that fighters were sent and found nothing. The Milwaukee “ball of fire” with a flame behind it, seen from 75 miles apart, reads much like a bright meteor. A three-hour light seen from Ohio fits a planet, and a fast object that six observers each described differently fits one too. These are possibilities, not findings, and the history makes no finding of its own.
