This Federal Bureau of Investigation file section, 62-HQ-83894 Section 6 (serials 246 to 301), collects FBI memoranda and correspondence from 1950 to 1952 on flying saucers. It covers green fireballs and discs seen near sensitive installations in New Mexico, Dr. Lincoln LaPaz's analysis, and the Air Force's Land-Air study known as Project Twinkle. It also holds an OSI summary, a USAF directive on reporting unconventional aircraft, a dissolving object reported by Philadelphia police, and letters from members of the public.

From the source:Release of 2026-05-08 Incident: N/A, N/A. The FBI's 62-HQ-83894 case file includes investigative records, eyewitness testimonies, and public reports concerning Unidentified Flying Objects and flying discs documented between June 1947 and July 1968. The records include high-profile incident accounts, photographic evidence from sites like Oak Ridge, TN, and technical proposals regarding potential propulsion systems. Additional topics include convention programs, researcher accounts, and extensive media coverage from the period. This file is partially posted on FBI vault with more redactions and some pages missing. Included here is the complete case file with several newly declassified pages and only minor redactions.

# THE TRUTH ABOUT FLYING SAUCERS

One of America's leading astronomers goes into his laboratory at Harvard and disposes of the flying-saucer myth. He adds simple instructions for making flying saucers in your own kitchen

By Dr. DONALD H. MENZEL

Donald H. Menzel is professor of astrophysics and associate director of solar research at Harvard University. His work on flying saucers was done in response to a request from LOOK. The Air Force has expressed a lively interest in it.

I SUPPOSE that I should be especially well qualified to write about flying saucers since I happen to be one of the few persons who has actually seen one.

My solar studies take me frequently to Colorado and New Mexico, and I was at the Holloman Air Base, near Alamogordo, N. M., at the height of the flying-saucer scare. That very morning, I had glimpsed what seemed to be several saucers moving overhead-until I focused my eyes more clearly and recognized the objects as weather balloons. That afternoon, I expressed my belief that most of the

saucers could be thus explained. But others in the group--including several well-known scientists-indicated that there was probably more to the saucer story than that.

Early that evening, I had my second attack of saucers. I was in the back seat of an automobile, being driven toward Alamogordo and admiring the full moon as it rose over Sacramento Peak toward the east. A few degrees north of the moon, I noticed what seemed to be a bright star, and then a second star not far from the first. Casually, I assumed that they were Castor and Pollux in the constellation of
