CIA File of the Day
Unidentified Flying Object
A CIA abstract of an article by F. Zigel, a doctor of technical sciences and assistant professor at the Moscow Aviation Institute, titled "Unidentified flying object," published in Soviet Life, no. 2, 1963, pages 27-29. Zigel presents several striking UFO observations and disputes the view of U.S. astrophysicist Menzel and others that, until recently, no scientific study of UFOs had been made in the Soviet Union.
