Air Intelligence Information Report: UFOB Sighting, Oklahoma City, Oklahoma, 6 May 1956

This report details an investigation into an Unidentified Aerial Phenomena (UAP) sighting that occurred on May 6, 1956, in Oklahoma City, Oklahoma. The investigation was conducted by the 4602d Air Intelligence Service Squadron. Three witnesses, including a 2nd Lieutenant in the USAF and a retired physician, reported observing a bright, orange-colored, teacup-shaped object in the northwestern sky for approximately 50 minutes. The witnesses described the object as being rimmed with lights, pulsating, and moving in a zig-zag pattern before eventually disappearing over the western horizon. The witnesses were interviewed extensively, and their accounts were considered reliable due to their backgrounds and the forthright manner in which they provided information. The investigation included checks with multiple Air Force bases, civil airports, and radar units, all of which yielded negative results regarding unusual aircraft or radar tracks. The Oklahoma State Weather Service and Tinker Air Force Base Weather Service were also consulted, confirming that no weather balloons were released during the sighting period. Meteorological data indicated that two temperature inversions were present at the time of the sighting. The investigating officer, Captain Louis Monroe, concluded that the sighting was likely an optical phenomenon. Specifically, the report suggests that the object was the first-magnitude star Capella, which was visible in the sky at the time, and that its appearance was distorted by the atmospheric conditions and temperature inversions known to be present. This conclusion was concurred with by the approving officer. The report includes sketches provided by the witnesses illustrating the object's shape and its movement pattern.
