Unidentified flying object

This document, authored by F. Zigel, a Doctor of Technical Sciences and Assistant Professor at the Moscow Aviation Institute, serves as an intelligence assessment regarding the scientific study of Unidentified Flying Objects (UFOs) within the Soviet Union. Zigel refutes the theories of U.S. astrophysicist Menzel, asserting that UFOs are not merely optical phenomena but are legitimate subjects for scientific inquiry. The document notes that in 1967, a group of scientists, military personnel, and public figures formed the UFO Section of the All-Union Cosmonautics Committee, chaired by Air Force Major General Porfiri Stolyarov, to investigate these phenomena. The author posits that UFOs exhibit 'sensible' behavior, such as maintaining formation flight and maneuvering to avoid direct contact, suggesting they may be conducting reconnaissance. A significant portion of the assessment focuses on the 1908 Tunguska event. Zigel references studies by the Joint Institute of Nuclear Research at Dubna and the USSR Academy of Sciences, which suggest the Tunguska body exhibited flight maneuvers and left residual radioactivity, leading to the conclusion that it was an artificial craft from another planet. The document concludes by calling for a global, objective, and scientific approach to the study of UFOs, urging the international community to set aside biases and pursue international cooperation to address the implications of these phenomena.
