Unspecified over Gwinner, ND
Investigated by a competent body and left unresolved. The rarest grade, and never awarded by us — only recorded.
The report, as filed
Gwinner, North Dakota. 7:30 a.m. Witness: Rotenberger. One silvery-grey ellipse with a clear bubble protruding from its top, hovered about a mile away, then landed within 300 yards and took off very fast. It made a low-pitched whine during the 5 minute sighting.
Held as-reported from Project Blue Book, United States Air Force. Witness text is preserved verbatim, including its spelling; nothing is edited beyond formatting.

Sightings from the Project Blue Book era (through 1969) live in Record Group 341 at the National Archives. Through Aletheca, the house instrument, anyone can commission the request — filed, chased, and published in the open, refusals included. The draft goes over already written: the records sought, and the date window they would live in.
