Project 10073 Record Card — Villa Grove, Colorado, 24 June 1957

This document is a Project 10073 record card detailing a UFO sighting reported on 24 June 1957 in Villa Grove, Colorado. The witness, a civilian, reported observing a single object for a duration of two hours. The object was described as being round at the bottom and star-shaped on top, approximately the size of a volleyball, and bright gold in color. The witness reported that the object exhibited a straight flight path with no maneuvers before drifting behind mountains. The weather conditions at the time were reported as clear. The report includes a section for conclusions, which identifies the event as a balloon observation. The file also contains supplementary materials, including a Skew T, log p diagram used for atmospheric analysis, and an overlay showing aircraft plots from the night of 23 June 1957. Additionally, there is a sketch drawn by Captain James E. Sullivan, Direction Center Chief of the 668th AC&W at Mather AFB, depicting the positions and tracks of the planets Jupiter and Saturn on the night of 23 June, which appears to be provided as context for the sighting. The report was processed by ATIC, and Captain Eugene Maxwell, an intelligence officer, noted the possibility of it being a weather balloon. The documentation includes various technical meteorological charts and administrative notes regarding the tracking of objects in the area during that period.
