Project 10073 Record Card — Sighting 400 Miles South of Minneapolis, Minnesota
AI-Generated Summary
A B-47 crew reported an unidentified object with running lights following them for 400 miles. Radar failed to confirm the object, and it remains officially unidentified.
On June 1, 1954, an unidentified aerial object was reported by the crew of a B-47 aircraft (AF 6597) approximately 400 miles south of Minneapolis, Minnesota. The object, which appeared to have running lights, was observed following the aircraft at altitudes ranging from 24,000 to 44,000 feet. The sighting occurred over a duration of approximately 400 nautical miles. A second aircraft, AF 6559, also a B-47, was in the vicinity on an IFR flight plan from Barksdale to Minneapolis. The crew of AF 6559 was requested to extinguish their running lights to help identify the object, but the object remained visible to the crew of AF 6597. Despite the visual reports, Air Defense Command (ADC) radar sites in the Minneapolis area were unable to verify the existence of the object. Weather conditions at the time were reported as 41 broken clouds with visibility exceeding 15 miles. The incident was documented on a Project 10073 record card and a CIRVIS report, ultimately resulting in an 'UNIDENTIFIED' classification.
