FBI Memoranda and Air Force Directive Regarding Unidentified Aerial Phenomena Observations in New Mexico and Philadelphia, 1950

Description

A 1950 compilation of FBI memoranda and an Air Force directive (AIFOIC-CC-1) addresses unidentified aerial phenomena, including 'flying saucers' and 'green fireballs.' It summarizes approximately 150 observations in New Mexico since December 1948 and details a September 26, 1950, Philadelphia incident where police witnessed a 'lavender' round object disintegrate. The document also includes Dr. Lincoln La Paz’s inquiry into potential USSR-originated guided missiles and the FBI Albuquerque office's conclusion that the phenomena's identity remained unascertained. A handwritten note speculates on 'flying saucers' propulsion.
