Analysis — our summary

On April 17, 1958, at 4:08 PM, a civilian witness identified only as WEAVER (age 23, with Civil Air Patrol background) telephoned the FBI Detroit field office to report seeing a circular object passing northward from the southwest across Detroit. The object had a crystal-type dome on top that reflected light. It crossed the witness's position approximately 3 blocks south of Six Mile Road at Lamphere Street. The FBI Detroit memorandum was authored by SA Robert Thomas Reynolds and addressed to the SAC Detroit.
