Project 10073 Record Card and Incident Report — September 1957

This document consists of a Project 10073 record card and a related teletype message concerning a UFO sighting on September 17, 1957. The initial report, filed under Project 10073, describes a single object observed for 15 to 20 minutes in Grayville, Illinois. The object was noted to have vapor trails and followed a flight path from North to South to West. The official conclusion on the record card states that the sighting was possibly caused by an aircraft, though it is also noted that there is no further report in the file. The second part of the document is a teletype message sent from the 337th Fighter Group in Portland, Oregon, to various Air Force commands. This message details a sighting by a witness in Gresham, Oregon, at 1930 hours. The witness, identified as a realtor, described a round object with a white color and a red edge. The red edge reportedly faded and brightened at intervals. The object was observed with low-power binoculars and appeared to move directly to a position, though it seemed much further to the west. The teletype includes standard reporting data, noting clear weather conditions. A handwritten annotation on the third page of the document suggests an alternative explanation, stating 'Prob. balloon' and noting that weather balloons are often seen at dawn or dusk. The document serves as a record of military processing for aerial phenomena reports during the late 1950s.
