Summary of Sightings of Unknown Aerial Phenomena, 17th District OSI (cont)

This document is a summary report from the 17th District Office of Special Investigations (OSI) of the United States Air Force, dated May 25, 1950. It addresses the ongoing observation of unexplained aerial phenomena, specifically 'green fireballs,' in the New Mexico area from December 1948 through May 1950. The report highlights that these sightings have been consistently reported by reliable observers, including scientists, military personnel, and airline pilots. The OSI established an organized reporting plan in December 1948 due to the frequency of these events. The report details the involvement of Dr. Lincoln LaPaz, Director of the Institute of Meteoritics at the University of New Mexico, who has served as a consultant for the investigations. Several conferences were held at Los Alamos involving various military and government agencies, including the FBI and the Atomic Energy Commission, to discuss the green fireball phenomena. While no logical explanation for their origin was found, the consensus was that the phenomena are real and require scientific study. The Geophysical Research Division of the Air Materiel Command has contracted Land-Air, Inc. at Holloman AFB to conduct a limited scientific study. The report concludes by reiterating that these phenomena continue to occur in the vicinity of sensitive military and government installations, which remains a cause for concern. The document includes extensive tables summarizing various sightings, detailing characteristics such as time, location, color, and duration, and includes correspondence and analysis regarding the phenomena.
