April 1947 — four anchor cases: ten objects over Tucson, Arizona, a Weather Bureau meteorologist's tracked disc over Richmond, Virginia, Bruno Cornacchiola's Tre Fontane encounter near Rome, and a French motorist's lens-shaped disc. thinkaboutitdocs.com.
1947: April UFO|UAP & Entity Sightings Archive
April 1947 is a genuinely strong month by this archive’s sourcing standards — French, American, and Italian cases each traceable to named investigators, official records, or established catalogues, two full months before Kenneth Arnold’s sighting would make any of this a national conversation. The Weather Bureau meteorologist tracking a silvery disc through a theodolite in Richmond, Virginia, and an Oklahoma City field engineer’s detailed account of an object three times faster than a jet, are both preserved in official FOIA and FUFOR Index records. In Tucson, two women watched nine discs and a tenth object dance in and out of an unnatural cloud for several minutes — and near Rome, a hardened anti-Catholic with a dagger in his pocket had an experience that converted him on the spot, later reinterpreted by ancient-astronaut author Erich von Däniken as an entity encounter rather than the Church-recognized Marian apparition it is more conventionally understood to be.
Date: April 1947
Location: Port Alberni, British Columbia, Canada
Time: Unknown
Summary: Objects were observed; animal reactions were reported. More than one bright metallic disc was observed by two witnesses for over one minute (Linton), flying rapidly to the east on edge. Chickens and ducks reacted visibly to the objects.

Date: April 1947
Location: Col de Serre, near Falgoux, Cantal, France
Time: 08:15
Summary: M. Maxime Orliange, while driving, observed an object resembling a lens-shaped disc with a cupola, flying on an ascending, sloping path above him. Blue light emanated from the junction of the cupola and the disc. The object appeared to be roughly 30 meters in diameter; when it reached a distance of about 400 meters, it disappeared on a near-vertical departure path.

Date: April 1947
Location: Richmond, Virginia
Time: 11:00
Case Status: Unexplained
Summary: Weather Bureau meteorologist Walter A. Minczewski saw a silvery disc through a theodolite while tracking a “pibal” (pilot balloon) weather balloon. The object, traveling east to west at an altitude of less than 15,000 feet, appeared distinctly larger than the balloon being tracked.
Source: Dr. James E. McDonald, 1968, direct interview with Minczewski; FOIA; FUFOR Index Source Status: VERIFIED — named, credentialed federal government witness, later personally interviewed by a physicist investigating the broader 1947 wave; widely cited as one of the strongest pre-Arnold American cases.
Date: April 1947
Location: Oklahoma City, Oklahoma
Time: 20:30-21:00
Summary: Field Engineer Savage observed a frosty white, round and flat object, with a diameter-to-thickness ratio of roughly 10:1, comparable in size to a B-29 (approximately 140 feet), traveling north on a 350-degree heading at an altitude of 10,000-18,000 feet, at roughly three times the speed of a jet (an estimated 1,800 mph), with a slight swishing sound. Observed for approximately 30 minutes.
Source: FOIA; FUFOR Index Source Status: PLAUSIBLE — traceable to declassified federal record indexes, though this archive could not independently verify the witness’s full name or additional corroborating detail beyond the compiled entry.
Date: April 5, 1947
Location: Santaquin, Utah
Time: Night
Summary: One object was observed briefly by four witnesses.

Date: April 11, 1947
Location: Bradshaw, West Virginia
Time: 15:00
Summary: A flying disc was observed. One silver disc was observed by a female witness for two minutes.

Date: April 12, 1947
Location: Tre Fontane, near Rome, Italy
Time: Afternoon, approximately 16:00
Summary: Bruno Cornacchiola, a former Catholic turned militant anti-Catholic activist, and his three children reportedly encountered a female entity in the grotto of Tre Fontane, described as wearing a white dress with a green cloak and holding a small book, interpreted as the Virgin Mary. Cornacchiola, who had been planning an assassination attempt against Pope Pius XII, was converted on the spot.

Editorial note: This is a well-documented, extensively corroborated historical event — the Tre Fontane apparition is formally recognized by the Catholic Church (informally approved by Pope Pius XII in 1947) and remains an active pilgrimage site. The entity description above matches the extensive Church-preserved record closely. Von Däniken’s framing of the encounter as an unexplained entity contact reflects his own ancient-astronaut reinterpretation of the event, not the event’s conventional historical or religious understanding; this archive preserves it as a documented “high strangeness” account per established editorial practice, without endorsing either the religious or extraterrestrial interpretation over the other.
Date: April 26, 1947
Location: Rothois, Picardie, France
Time: 21:30
Summary: Objects with an appearance and performance beyond the capability of known earthly aircraft were sighted. Several balls of light, roughly 0.6 meters across, followed three girls along a curving road for ten minutes, vanishing as the girls approached home.

Date: April 29, 1947
Location: Tucson, Arizona
Time: 13:20
Case Status: Unexplained
Summary: Two women, Mrs. Olavick and Mrs. Down of Tucson, Arizona, watched nine white discs and a tenth object moving behind a steamy, unnatural cloud in an otherwise completely clear sky, arranged in a V-shaped formation. The ten objects moved up and down erratically and in and out of the cloud for 5-6 minutes. [Full Report]

EXECUTIVE SUMMARY
April 1947 — The Strongest Pre-Arnold Month Yet
This is one of the better-sourced months in this archive’s early-1947 record. The Richmond, Virginia Weather Bureau case is especially notable — a federally employed meteorologist tracking a genuine weather balloon through professional survey equipment when a second, larger silvery object appeared alongside it, later personally interviewed by physicist James McDonald two decades on. The Tucson, Arizona case is this month’s most vivid single account, preserved not through popular UFO literature but through a formal RAND Corporation research document — an unusually institutional pedigree for a 1947 sighting. This revision also flags, without disputing, the Tre Fontane entry’s framing: the underlying event is a thoroughly documented, Church-recognized historical occurrence, and Erich von Däniken’s characterization of it as an entity encounter reflects his own well-known interpretive lens rather than how the event is conventionally understood.
“The ten objects moved up and down in an erratic manner, and in and out of the unnatural cloud for 5-6 minutes.”
