September 1953's brief but well-documented record, archived by date.
1953: September UFO|UAP & Entity Sightings Archive
September 1953 is a short month in this archive’s record, but its strongest entry carries real weight: a witness in Tonnerre, France watching two landed craft and three helmeted entities depart together, one of the vehicles extending wing-like panels before tilting upright for takeoff — documented by Jacques Vallée, one of ufology’s most methodical researchers, and corroborated by physical traces left at the scene. Alongside it sit a blue light rising from the sea off Santander, Spain, a brief and unsettling attempted-abduction report from Denmark, and a thinly-documented Montana sighting that shares its town, though apparently not its date, with a much richer crash claim already on this archive.
Date: September 1953
Location: Santander, Spain (Latitude 43-28 N, Longitude 3-48 W)
Time: Unknown
Summary: On a clear night, witness Sr. F. Campaña saw an object rise from the sea approximately 3,500 m away at a 75-degree angle. The object appeared solid and was bright blue in color. It rose sharply toward the northeast for one minute before being lost to sight.

Date: Fall 1953
Location: Dutton, Montana
Time: 19:00
Summary: An object was observed by a 53-year-old male witness for eight minutes. Electromagnetic effects were noted, and men in black later interviewed witnesses. Note: Dutton, Montana is also the location of a separate, more fully documented standalone case on this archive, “1953: UFO Crash near Dutton, Montana” — but that case is dated October 13, 1953, with a different witness (Cecil M. Tenney) and different circumstances. Given the different dates and details, these read as two separate incidents sharing a town rather than one case double-counted, though the overlap is worth noting.

Date: September 4, 1953
Location: Tonnerre, France
Time: 21:30
Summary: A woman saw two objects on the ground and three entities, about 1.5 m tall with oversized heads, wearing helmets and boots, running toward them. One entered the elongated object, 5 m long and 1.5 m wide, which spread “wings” that made it look like a butterfly. It then took a vertical position, resting on a tripod, and took off together with the spherical object into which the other two entities had gone. Traces were found at the spot. [Full Report]

Date: September 12, 1953
Location: Brovst, Denmark
Time: Unknown
Summary: Two humanoids with scaly, rugged, gold-colored skin and cold, fish-like hands jumped out of nearby bushes and attempted to abduct a girl. Both beings also emitted a bright golden light from their bodies. The girl apparently got away. No further information survives.

EXECUTIVE SUMMARY
A Short Month, Anchored by One Well-Documented Case
September 1953 is the thinnest month in this archive’s 1953 record, with only four entries — but two of them, sourced independently to Jacques Vallée, carry real weight despite their brevity. The Tonnerre, France case in particular pairs a genuinely unusual mechanical detail (a craft extending wings before takeoff) with physical trace evidence, giving it more to stand on than most single-witness accounts this short.
The Dutton, Montana entry is worth a specific note: it shares a town with a much more elaborate crash claim already documented elsewhere on this archive, but the two accounts differ enough in date and detail that they read as separate incidents rather than one case told twice.
“One entered the elongated object… which spread ‘wings’ that made it look like a butterfly.”
— Jacques Vallee, “Passport to Magonia,” September 4, 1953
