Incident #22 Sighting Report — Spokane, Washington, 21 June 1947

This document contains a Project SIGN record regarding a sighting that occurred on June 21, 1947, in Spokane, Washington. A civilian observer reported seeing a shiny, silvery object, described as a disc or flash of light, while in their yard shortly before noon. The observer noted that the object appeared to be quite large and was traveling south, slightly to the west, at an altitude estimated between 7,000 and 8,000 feet. The observer initially thought the object might be a plane, but noted it was flying slower than a two-motored aircraft and was flashing intermittently. The observer also noted that the object appeared to be traveling against prevailing winds. The official analysis of the incident, conducted by the Air Materiel Command, concluded that the information provided was too limited for a definitive interpretation, but suggested that the objects might possibly have been a series of balloons. This incident is included in a list of sightings compiled by Project SIGN that were considered to have the greatest possibility of being balloons. The document includes a formal record form, a narrative account from the witness, and correspondence from the Air Materiel Command to the Air Weather Service regarding the collection and interpretation of data related to unidentified flying objects.
