Washington, D.C., September 1952September 1952

On the night of September 12, 1952, a bright streak of light crossed the sky over Washington, D.C., and surrounding areas, triggering a wave of telephone calls to police, newspaper offices, and government agencies. The object appeared as a silvery white, spherical shape with a reddish or orange tail. Multiple witnesses across Washington, Virginia, Maryland, and other nearby states reported seeing it descend at a steep angle, moving in a northwesterly direction. Most observers said it moved horizontally across the sky and came down very low, looking to some like a roman candle firework seen at close range. One witness, a security officer at the Joint Chiefs of Staff, described a spinning, phosphorescent ball with a brilliant silvery white appearance, observed for about two seconds at an altitude of 43 degrees, appearing roughly three miles away.

The Air Force's radar systems at Washington National Airport and Andrews Air Force Base detected nothing, reporting no radar signals during the time of the sighting. Weather conditions at the time were clear, with excellent visibility reported at seven to nine miles. The Baltimore Weather Bureau, flooded with calls, initially described what witnesses saw as "a great greenish white light." However, the National Weather Bureau quickly offered a conventional explanation, suggesting the object was a meteor. The Naval Observatory spokesman agreed, calling it "a typical meteor," and National Airport officials stated flatly that the object was not a flying saucer.

The case file includes detailed witness questionnaires from at least ten observers in the Washington area, each providing slightly different descriptions but generally agreeing on the object's bright coloration, downward trajectory, and lack of sound. One witness reported the object was large enough to cover "from the top of the wrist to the knuckle" when viewed at arm's length. Another noted the object appeared to be at no more than 2,500 feet in the air. No aircraft were involved, and no obvious physical evidence was recovered. The lack of radar confirmation, combined with the absence of any debris or landing site, made verification difficult.

Subsequent sightings over Washington continued into late September. On September 13, another witness reported seeing a circular, silvery, glowing object moving slowly over the center of the city, lasting 34 to 45 seconds, with no wings or vapor trails. On September 20, a bright blue white light was sighted traveling at high speed from north to south over northwest Washington, visible for only about half a second. That observer reported the object appeared to "follow the curvature of the earth."

The Air Force's official conclusion in this case was "Probably Balloon" or, in some instances, "Probably Astronomical," reflecting the meteorite hypothesis. However, the file notes that some reports lacked sufficient detail for a preliminary evaluation. No conclusive explanation was confirmed by the Air Force.
