Project 10073 Record Card and Disposition Form — Sighting of 5 July 1956

This document contains a Project 10073 Record Card and subsequent internal military correspondence regarding an unidentified aerial phenomenon reported on 5 July 1956 near Skagway and Juneau, Alaska. The sighting, which lasted approximately one minute, involved a single object observed by personnel at a CAA control station. The witness described the object as a dark, oblong silhouette against a cirrus cloud background, moving at a speed estimated to be twice that of a DC-6 aircraft. The report contains conflicting details, noting both that the object had no visible wings or tail, yet also describing three bumps on the wings that resembled engine nacelles or jet pods. The object was observed from both the broadside and the rear. Weather conditions at the time included scattered clouds and light rain showers. Following the initial report from the 5004th Air Intelligence Service Squadron, the Air Defense Command requested further information, specifically inquiring if the object could have been a Soviet aircraft violating U.S. airspace. In response, the AFOIN-4F2 division stated that there was no information on file regarding Soviet air activity in that specific area and noted that a CIA report on general Soviet Arctic activities did not provide a match. The final assessment by the investigating officers suggested that the report was likely of an aircraft, noting that the flight path and speed were consistent with aircraft analysis, although the specific description did not identify it as any known aircraft type.
