The Air Force standardized UFO reporting

This serial is the FBI's copy of U.S. Air Force Air Intelligence Requirements Memorandum Number 4, dated February 15, 1949, which set standing rules and procedures for reporting sightings of unconventional aircraft and unidentified flying objects, including the so-called flying discs. It is dry but important, because it tells people exactly what details to write down so a sighting can be checked later. Good UFO records depend less on wonder than on plain questions asked at the right time.
