Weird Stories, March 1948

This document is not a pulp magazine but rather a U.S. Air Force intelligence report on unidentified aerial phenomena, dated March 1948. It contains an incident report from Baltimore, Maryland, filed by an FBI office, documenting a confidential witness—a woman active in American Legion activities and wife of a former U.S. military officer—who reported hearing peculiar aircraft-like sounds between 3:00 and 5:00 a.m. over several weeks. The sounds differed from typical American airplane motors, resembling instead foreign aircraft engines. A neighbor confirmed similar observations. The report includes a checklist of incident details (mostly marked N/3, indicating no information) and concludes with Dr. Hynek's evaluations from Project Grudge, categorizing 244 incidents by astronomical probability, conventional explanations (balloons, aircraft, rockets, flares), and unexplained cases lacking sufficient evidence.
