1952 Uvalde, Texas Case: A Blue Book Unknown Witnessed by an Airline Station Manager
At 2:46 in the afternoon of July 22, 1952, Don Epperly — station manager and weather observer for Trans-Texas Airlines at Uvalde — looked up from his post to see a large, round, silver object hovering at an estimated 20,000 feet, roughly 50 feet across. For 45 seconds he watched it gyrate in place before it accelerated away at a speed he put at well over 1,000 miles per hour. It’s a short encounter, but it remains, to this day, one of Project Blue Book’s official “Unknowns” — a case the Air Force itself never managed to explain, witnessed by exactly the kind of trained, on-duty aviation professional whose reports carried the most weight.
Date: July 22, 1952
Sighting Time: 2:46 p.m. (1446 local)
Day/Night: Day
Location: Uvalde, Texas
Urban or Rural: Airport/aviation facility
No. of Entity(‘s): Not Applicable
Entity Type: Not Applicable
Entity Description: Not Applicable
Hynek Classification: DD (Daylight Disc)
Duration: 45 seconds
No. of Object(s): 1
Description of the Object(s): A large, round, silver object, observed gyrating in place before departing at high speed
Shape/Size/Color of Object(s): Round, approximately 50 ft in diameter, silver
Distance to Object(s): Not separately recorded; estimated via its altitude and apparent angular size
Height & Speed: Estimated altitude of 20,000 ft; departed at a speed estimated well in excess of 1,000 mph
Number of Witnesses: 1 (Don Epperly)
Special Features/Characteristics: The object gyrated in place for the full 45-second observation window before its sudden high-speed departure; the witness was a trained aviation weather observer on active duty at the time of the sighting
Case Status: Unresolved — officially carried as a Project Blue Book “Unknown,” cross-referenced consistently across multiple independent Blue Book compilations
Source: Berliner; Project Blue Book Unknown Case Files
Summary/Description: At 2:46 p.m. on July 22, 1952, Don Epperly, station manager and weather observer for Trans-Texas Airlines at Uvalde, Texas, observed a large, round, silver object at an estimated altitude of 20,000 feet, approximately 50 feet in diameter. The object gyrated in place for the full 45 seconds Epperly watched it before departing at a speed he estimated at well over 1,000 miles per hour. The case remains officially unresolved and is carried in Project Blue Book’s list of unexplained “Unknown” cases.
Related Cases: One of several daylight disc reports from trained aviation personnel during the same week of the 1952 flap (compare the July 22 Los Alamos, New Mexico sighting by control tower operator Don Weins and two CARCO pilots, and the earlier July 2 Tremonton, Utah Newhouse film)
Detailed Report
The Uvalde case is brief but carries real institutional weight, both from its witness and from its official classification. Don Epperly was not a passerby — he was the station manager and weather observer for Trans-Texas Airlines, meaning his professional duties at the time of the sighting involved active observation of sky and weather conditions as a matter of course.
At 2:46 p.m. on July 22, 1952, Epperly observed a large, round, silver object at an estimated altitude of 20,000 feet, roughly 50 feet in diameter. Rather than moving steadily across the sky, the object gyrated in place for the entire 45-second window of observation — a distinctive, sustained motion pattern rather than a brief glimpse of something already departing. At the end of that window, it accelerated away at a speed Epperly estimated at well over 1,000 miles per hour.
The case was formally logged and investigated by the Air Force, and — significantly — was never resolved to a conventional explanation. It appears consistently across every major independent compilation of Project Blue Book’s official “Unknown” cases, from Berliner’s original listing through later researcher catalogs, with the same core details (witness, time, object, duration, estimated speed) preserved intact across decades of retelling — a sign of a genuinely stable, well-documented original record rather than a story that accreted embellishment over time.
RESEARCHER’S NOTES
The Uvalde Case — A Trained Observer, a Formal Unknown Classification
- The witness’s professional role adds real weight to the report. A working aviation weather observer, actively on duty, is a meaningfully different category of witness than an untrained bystander — someone whose job specifically involved accurate sky observation.
- The official “Unknown” classification is itself significant. The Air Force investigated this case and explicitly did not resolve it to a conventional explanation — a status it has retained across every major subsequent compilation of Blue Book’s unresolved cases.
- The consistency of the case’s details across independent sources is a genuine strength. The same core facts — witness, time, altitude, size, duration, speed estimate — appear essentially unchanged across multiple decades of separate Blue Book compilations, suggesting a stable original record rather than a story that grew with each retelling.
- The case remains genuinely thin on independent corroboration. As a single-witness sighting, even a well-documented one, it lacks the additional evidentiary weight that radar confirmation or a second observer would add.
- The gyrating-in-place behavior, followed by sudden high-speed departure, is a recurring pattern across many of this month’s stronger cases. Worth noting as a shared behavioral signature across the wider 1952 wave rather than treating this case in complete isolation.
The Uvalde case is a compact, professionally witnessed daylight sighting that the Air Force itself was never able to explain — carried consistently, unchanged, across decades of independent Blue Book documentation. It remains exactly what its official classification says: unresolved.
“One large, round, silver object flew at more than 1,000 mph for 45 seconds, while gyrating.”
