1948: the year Project Sign went looking for an answer, from the Mantell crash on January 7 to the green fireballs of December.
1948: UFO|UAP & Entity Sightings by Month Hub
If 1947 gave the phenomenon its name, 1948 gave it consequences. On January 7, the Godman Field control tower in Kentucky is still trying to identify a large object reported by police and townspeople when pilot Thomas Mantell takes off after it and does not come back. Through the spring and summer the cases get harder to dismiss: pilots in the Philippines and Alabama, farmers in Ohio and Minnesota, and on July 24 the crew of an Eastern Air Lines DC-3 near Montgomery, Alabama, who describe a wingless, cigar-shaped craft with a row of windows. On October 1, a North Dakota Air National Guard pilot near Fargo reports a long aerial pursuit of a maneuvering light.
Behind the headlines, the Air Force’s Project Sign is collecting and weighing the reports, and by Ruppelt’s account its analysts draft a classified Estimate of the Situation that fall. Then the year closes in the New Mexico sky: green fireballs near Los Alamos and Sandia, an airliner crew taking evasive action on December 5, and Dr. Lincoln La Paz plotting paths that never lead to a meteorite. Radar operators, Counter Intelligence Corps agents and air base crews add their own reports from Fukuoka to Goose Bay to Andrews Air Force Base. This is the complete 1948 UFO sightings archive: twelve monthly indexes and an Unknown Date page, tracing the year Project Sign went looking for an answer.

PROJECT SIGN AND THE SEARCH FOR AN ANSWER
Who Was Watching in 1948
The Pilots. Mantell in January, Chiles and Whitted in July, Gorman in October and the Michigan C-47 crew in May: trained airmen at altitude remain the most persuasive witnesses of the year, and the Air Force treats their reports as the core of the problem.
The Radar Operators. The Fukuoka night-fighter crew, the Goose Bay ground-control operators and the Wakkanai station add instrument returns to eyewitness accounts, so that visual and radar reports begin to overlap in the same files.
The Investigators in the Field. The CIC at Hamel, AFOSI agents flying home from fireball searches, and Dr. Lincoln La Paz plotting trajectories across New Mexico show how seriously the reports are being worked on the ground.
The Intelligence Analysts. Project Sign’s staff weighs the cases and, by Ruppelt’s account, drafts the Estimate of the Situation. The Los Alamos sighting of September 23 is one of the cases he says it contained, and by early 1949 the project would be reorganized as Project Grudge.
The Public and the Press. Hundreds of Yakima residents phone the CAA in a single afternoon, Phoenix crowds watch four discs flip in sequence, and newspapers carry the “flying men” of Longview and the birdman of Chehalis.
The Hoaxes and Crash Claims. Aztec, the Tomato Man photographs with the Laredo crash claim, and the Dreamy Draw story all attach themselves to 1948. They are kept in the archive without a Hynek classification and are marked accordingly.
Across the twelve months, 1948 is the year the question changes from “what did they see?” to “what do we do about it?” The reports pile up on desks at Wright Field, the analysts form a view, the fireballs arrive over the Southwest’s most sensitive sites, and the official answer is still unsettled when the year ends. What survives is the record itself, and every month of it is here.
“No matter what these green fireballs were, the military was getting a little edgy.”
Edward J. Ruppelt, on the New Mexico fireballs of December 1948
