Project 10073 Record Card — Portland, Oregon, 17 June 1958

This document consists of a Project 10073 record card and associated teletype communications regarding an Unidentified Aerial Phenomena (UAP) sighting reported in Portland, Oregon, on June 17, 1958. The witness, an 83-year-old housewife, reported observing a round, shiny silver object, approximately the size of a full moon, with a haze around it. The object was seen climbing in a straight line toward the northwest at a speed compared to that of a jet. The observation lasted between two and three minutes. The report includes detailed meteorological data, noting a radiation inversion at 3,000 feet and a thin layer of smoke and haze. Military personnel from the 337th Fighter Group investigated the report and consulted with a weather forecaster. The official conclusion reached by the investigators was that the sighting was likely a reflection of sunlight off a surface, such as an automobile windshield, onto the smoke and haze layer at the inversion. The report further suggests that the observer's age and potential poor eyesight, combined with bright sunlight, may have led to the misidentification of a light aircraft as a round object. An additional handwritten note on the report concurs with this assessment, stating that the sun was in the correct position for such a phenomenon to occur.
