Project 10073 Record Card: Sighting Report - Portland, Oregon, 7 April 1957

This document consists of a Project 10073 record card and associated teletype communications regarding an aerial sighting on April 7, 1957. The primary report originated from the 25th Air Division at McCord Air Force Base, Washington, and was directed to the Air Technical Intelligence Center (ATIC) and the Director of Intelligence at USAF Headquarters. The sighting involved a single object described by a Ground Observer Corps (GOC) observer, Mrs. Edmonds of Allyn, Washington. The witness reported observing a very bright object, which she likened to a World War II buzz bomb, in the vicinity of Shelton, Washington, at 0215Z. The object was observed for two minutes, traveling in a southeasterly direction at an estimated speed of 250 to 300 knots, and was accompanied by a loud whistling noise. A second, related report for the Portland, Oregon area was logged at 0305Z. The official conclusion reached by the evaluating agency was that the object was a 'possible a/c' (aircraft), noting that numerous aircraft were present in the area at the time of the observation. The documentation also notes that a weather balloon was released in the Portland area at 0300Z, though the primary conclusion remains focused on the possibility of conventional aircraft.
