This document is not a pulp magazine; it is a declassified U.S. Air Force intelligence report (IR-32-53) dated May 14, 1953, concerning an unidentified flying object sighting. The report documents a ground observation made on March 11, 1953, near Seattle and Renton, Washington, viewed through a four-power rifle scope by civilian observers at approximately 19:10 PST. The object was described as round, white/opaque, marble-sized, traveling at unknown speed and altitude (estimated between 10,000-20,000 feet), silent, without exhaust trail or visible propulsion. The object shifted back and forth before disappearing over the horizon. The report notes high-altitude balloons were in the area; Seattle MATS radar facilities tracked a balloon, though the observation's length remains unknown.
