Project Blue Book Case #2337. On January 17, 1953, an unidentified object was reported over Guatemala — reaching Blue Book through intelligence channels from this Central American nation. The U.S. maintained significant intelligence interests in Guatemala, which would culminate in the CIA-backed 1954 coup. American military advisors and intelligence operatives in the country would have been the likely source of this report. The case was classified "Unknown" — one of Blue Book's most exotic Latin American entries.
