Officer Lonnie Zamora egg-shaped craft with humanoid figures — Socorro, New Mexico, April 1964

Socorro Police Officer Lonnie Zamora observed a shiny aluminum-white oval object approximately 150-200 yards south of a gravel road at approximately 5:45 PM on April 24, 1964, while pursuing a speeding vehicle. He initially mistook the object for an overturned car, then observed two humanoid figures in white coveralls near the object who appeared startled and quickly moved. The object rose straight up with a loud roar and a blue-orange flame beneath it, then traveled silently at 10-15 feet altitude, cleared a dynamite shack by approximately three feet, and disappeared over a mountain. FBI Special Agent D. Arthur Byrnes Jr. arrived at the scene the same evening and confirmed four rectangular depressions in the ground (16 by 6 inches, approximately 2 inches deep), three burned patches of grass inside the depression area, and three smooth circular marks approximately 4 inches in diameter in the sandy soil.

“"It looked, at first, like a car turned upside down. Saw two people in white coveralls very close to the object."; "Object was starting to go straight up--slowly up. Object slowly rose straight up. Flame was light blue and at bottom was sort of orange color."; "it has been the observation of Agent Byrnes that Officer Zamora, known intimately for approximately five years, is well regarded as a sober, industrious, and conscientious officer and not given to fantasy"”

Highly credible primary-source FBI field report. FBI agent Byrnes was on the scene the same evening and personally confirmed physical trace evidence. Zamora was independently vouched for by the agent who knew him for five years as a reliable, sober officer. Witnesses also present at scene: Socorro County Undersheriff Jim Luckie, Sgt. M.S. Chavez, Officer Ted Jordan (NM State Police), though they did not observe the object directly. OCR quality is moderate-to-poor for the latter two-thirds of the document (repetitive photocopied pages), but the first copy is clearly legible. The red insignia drawn by Zamora (described as approximately 2.5 ft high, 2 ft wide, on the mid-section of the object) is referenced in the text but the drawing itself is not included in the OCR text. Physical evidence (ground depressions, burned brush) was confirmed by multiple law enforcement personnel. This is one of the most thoroughly documented ground-based UAP incidents in declassified US records.
