South Haven, Michigan — USAF Radar Visual Blue Book Unknown

On March 8, 1967, officers from the South Haven Police Department and the Van Buren County Sheriff's Department observed a disc-shaped object maneuvering over Lake Michigan at approximately 5,000 feet. The officers tracked the object for approximately 20 minutes. USAF radar at Selfridge Air Force Base confirmed radar returns corresponding to the object's reported position. The radar data showed the object performing rapid accelerations and instantaneous stops inconsistent with any known aircraft of the era. Additional civilian witnesses in the South Haven area filed reports. Project Blue Book investigators examined the case. The simultaneous law enforcement visual observation and USAF radar tracking made the case compelling; Blue Book classified it as 'Unknown.' The case file, available through NARA Project Blue Book records, includes the officer statements, radar operator reports, and the Blue Book analyst's determination. The 1967 Michigan wave — which included the famous Ann Arbor/Dexter events — produced multiple officially classified 'Unknown' cases in a compressed geographic and time window, prompting the congressional inquiry that led to the Condon Committee.
