Project 10073 Record Card — 26 April 1963 Sighting

This document consists of a Project 10073 record card and a supporting Department of the Air Force staff message regarding an aerial sighting reported on April 26, 1963. The sighting was made by the crew of Northwest Airlines flight 25 at 0613Z, located at coordinates 27N 150W over the Pacific Ocean. The witness reported observing a single satellite-like object traveling in a north-to-south orbit. The speed and altitude of the object were reported as unknown. The official evaluation of the incident, documented on the record card, notes that ECHO data was not available to verify the sighting. Consequently, the object was assumed to be orbital by the observers, and the case was officially evaluated as a satellite based on limited data. The staff message, originating from the 326 Air Division at Kunia Facility, Hawaii, confirms the details of the report and notes that there was no argument on the case, although it mentions a potential discrepancy regarding the date and the use of 'Echo' data for identification. The document includes a technical table of satellite data for the period, which appears to be reference material used for the evaluation.
