Analysis of Flying Object Incidents in the US 1948

Summary

DOW-UAP-D093 is the 67-page analysis 'Analysis of Flying Object Incidents in the U.S.,' Air Intelligence Division Study No. 203 of 10 December 1948, prepared by the USAF Directorate of Intelligence and the Office of Naval Intelligence. The report reviews roughly 210 reported incidents and notes that observers included trained and experienced weather service personnel, USAF-rated pilots, and civil aviators. It recognizes that reports were influenced by earlier unidentified flying object sightings, particularly over Scandinavia in 1946, and that unknown objects could not be identified on the basis of reported information. The study considers possibilities including weather balloons, rockets, known aircraft, and celestial phenomena and discusses whether objects might be of domestic or Soviet origin, mentioning aircraft such as the Northrop B-35 and YB-49.
