This is not a pulp magazine but an official U.S. Air Force UFO report form (ATIC Form 329) documenting a sighting near Colorado Springs on April 9, 1957. The record describes a ground-visual observation of one object approximately half the size of a C-47 aircraft, characterized as white or shiny silver, that hovered near a C-47 before moving due east and disappearing. The observation lasted between 09718154 and 560 seconds. The C-47 pilot did not observe the object. The form notes possible balloons in the area per Conad Force East Center. The conclusion marked is "Insufficient Data for Evaluation," with "Possibly Balloon" also indicated as a potential classification.
