UFO photos taken during the American flying saucer wave of 1952

This is one of the most famous photos taken during the American flying saucer wave of 1952. It was taken by Shell Alpert, a U.S. Coast Guard (USCG) seaman stationed at the USCG weather office in Salem, Massachusetts, on July 16. The USCG briefly investigated the case and issued a press release. Afterwards, the original negative was sent to Project Blue Book for analysis. The official air force report stated, "The photo was taken with a 4/5 Busch Pressman Camera . . . loaded with 4/5 super XX cut film. The photographer observed several lights which seemed to be wavering. He observed the lights for 5 or 6 seconds and grabbed the camera which had been on a nearby table."
