30th Air Division History, 1950: Guards See an Object at an AEC Gate

What this record is

This is a short run of history pages from the 30th Air Division (Defense) at Selfridge AFB, Michigan, one of the Eastern Air Defense Force divisions that ran radar stations and interceptor squadrons across the Great Lakes and the upper South in 1950. The PDF has 20 pages copied from microfilm, and roughly half of them are blank or unreadable. The readable pages hold an October 1950 history statement from the division’s combat operations section (page 8 of the PDF), monthly headquarters squadron reports for November and December 1950 by the division historical officers Lt Col A. W. Eberle and Capt C. L. Gardner (pages 10 to 13), and summaries of September and October alert tests, scrambles and fighter readiness (pages 14 to 16). The file was classified SECRET.

The reason it is in a UAP transfer is one paragraph on page 8.

What it says about UFOs

Page 8 of the PDF has the only UFO passage. After routine entries on alert tests and fighter moves, the October statement has a heading, “Incident Reported by Atomic Energy Commission Guards”. It says that on 15 October the Atomic Energy Commission reported to Station 47 an unknown object at the main gate of the AEC. Two guards saw it and described it as bullet-shaped with a ribbon “tale” four to six feet long. It was hovering below fence level, and when a guard came within fifty feet it took off over the fence and disappeared over a hill. The object seemed to grow larger as it rose and made no noise. The incident was reported to Eastern Air Defense Force. That is all the division recorded.

The paragraph does not say which AEC installation was involved or where Station 47 was. The likeliest answer is Oak Ridge, Tennessee. NICAP’s chronology of the Oak Ridge sightings lists an incident on the afternoon of 15 October 1950 near the Solway Gate there. AEC security men saw a shiny object shaped like a bullet or bladder, trailing smoke, hover a few feet off the ground about fifty feet away. The date, the shape and the fifty-foot distance all match this paragraph. The division’s own pages point the same way, since page 16 lists F-82 night fighters on alert at McGhee Tyson, the Knoxville airport about twenty-five miles from Oak Ridge. The identification is therefore very probable, but it is an inference and not something this record states. The research site Project 1947 has published a transcription of this paragraph from the division’s history.

The rest of the file has no UFO content. In October the division flew 31 active air defense scrambles (page 8), and 36 in September (page 15). The history does not tie any of them to this incident.

Context

October 1950 was a busy month at Oak Ridge, the AEC’s uranium enrichment complex. Radar at McGhee Tyson picked up unidentified returns, fighters were scrambled, and AEC security officers made repeated visual reports. The FBI documented the same wave in files released in 2026 and covered on this site, such as the Oak Ridge radar reports of 12, 15 and 16 October 1950. The division’s next surviving history, for October to December 1951, records more sightings, including another at Oak Ridge. At the time the Air Force’s UFO effort was Project Grudge, which was at its lowest ebb in 1950. Air defense units reported sightings through their own channels, as this one did to Eastern Air Defense Force.

Status

The record adds an Air Force air defense copy of an incident better known from AEC and FBI files. It confirms that the report reached the air defense system within the month. It records no investigation, no radar data and no conclusion. What the guards describe is a small, silent object that hovered low and had a long streamer. That fits a kite or a small balloon trailing a tail at least as well as anything exotic. The detail that it seemed to grow larger as it went up runs against a simple balloon, but a single second-hand paragraph cannot carry that much weight.
