Roswell — US Air Force 1994 Official Investigation Report

In September 1994, the US Air Force released 'The Roswell Report: Fact Versus Fiction in the New Mexico Desert' — a formal official investigation responding to Congressional pressure after GAO investigator staff began looking into allegations about the 1947 Roswell incident. The report concluded that the debris recovered in July 1947 was from Project Mogul, a classified program using high-altitude balloon arrays to monitor Soviet nuclear test acoustics. The report documented extensive classified program history and physical characteristics of the Mogul balloons consistent with descriptions of recovered debris. In 1997, a follow-up report 'The Roswell Report: Case Closed' addressed persistent accounts of alien bodies by attributing them to anthropomorphic test dummies used in high-altitude parachute experiments from the early 1950s — approximately the right time period for some witnesses' memories. Both reports remain the US government's official public position on Roswell. Both are formal DoD documents available at NARA. The 1994 and 1997 reports were the result of the General Accounting Office (GAO) investigation that also revealed most RAAF administrative records from July 1947 had been destroyed — a destruction of records the GAO characterized as improper. The reports represent the most recent formal US government statements on the most-studied UAP-related incident in American history.
