65 HS1-101634279 100-DE-18221 Serial 844

FBIIncident: April 17, 1958Detroit, MI266 KB

An FBI memo from 1958 reporting a UFO sighting by a Detroit man who described a "circular object with a crystal-type dome," and recommending that the information be forwarded to "proper air force authorities."

The description is the government’s own, from war.gov/UFO, released on May 8, 2026. The Pentagon calls these unresolved cases — publishing a file does not mean it shows anything anomalous.
