Incident #200, 200a, 200b, 200c — Crescent City, California, 17 October 1948

This document compiles reports and correspondence regarding a series of sightings of an unidentified flying object near Crescent City, California, on 17 October 1948. Four witnesses, including a fisherman, a barber, a dry cleaner, and a housewife, reported observing a silver, egg-shaped, metallic object at approximately 1610 hours. The witnesses, who were interviewed by the U.S. Coast Guard, described the object as having no visible wings or tail structure, traveling at high speed in a southerly direction, and performing a sharp 45-degree banking turn. The object was estimated to be at an altitude between 5,000 and 25,000 feet and was visible for two to five minutes. The Coast Guard forwarded these reports to the Air Materiel Command at Wright-Patterson Air Force Base as part of Project Sign. The Air Force requested further investigation and specific details from the witnesses. Subsequent correspondence between the Navy and the Air Force clarified that the Navy had not operated airships on the West Coast since 1947, effectively ruling out a Navy blimp as the source of the sighting. The document also includes a brief mention of another incident, #186, involving a sighting near Sterling, Utah, on 16 October 1948, where an observer reported a small, black object with a silver stripe traveling at high speed. The official evaluation for the Crescent City incident suggests the object could have been an advertising blimp, a balloon, or an aircraft, though the banking maneuver made a balloon less likely. The document concludes with the official statements of the witnesses, all of whom were deemed reliable and of good character by the investigating officer, Cecil Mac Leod of the U.S. Coast Guard.
