A Pan Am Crew's Orange Cylinder North-west of Boston

The Pan American Constellation was at 8,000 feet on its way from Gander to La Guardia on the afternoon of 4 August 1947. Walter I. White, the navigator, was sitting in the co-pilot's seat. He noticed a deep-gold object well below them that reflected the light. It was elliptical and blunt at both ends. He watched it for almost fifty seconds before he told the captain.

Capt. Alphaeus O. Powell then saw something on his own side, the left, about a mile away and below. It was a bright orange cylinder about the length of a P-40's fuselage, blunt at both ends, with no sign of exhaust. He put its speed at about 160 miles an hour on a heading of 200 degrees. He banked the aircraft to keep it in view for about fifty seconds, until a cloud came between them.

What is on the record

The account comes from Air Defense Command interview summaries dated 12 and 15 September 1947. They are kept in Serial 130 of the FBI's flying-disc file 62-HQ-83894, released by the Department of War. The summaries place the aircraft midway between the Everett fan marker, three miles north-west of Boston, and the Bedford radio beacon, fifteen miles north-west. That puts the sighting over land about ten miles from the city. The archive's machine summary had it "off Boston", and that was wrong.

The two men did not describe one simple event. White estimated 176 miles an hour on an easterly course. Powell gave 160 on 200 degrees. White did not think Powell's object was the same one he had seen. The file may hold two observations of two objects. It offers no evaluation of either.

Outside the file the sighting appears in Overmeire's catalogue as "near Boston", drawn from the FBI document via Bruce Maccabee. That is the only outside listing found.

Why it sits where it does

L4 · OFFICIAL RECORD: a released government record names who saw it. Powell and White are the two it identifies, both Pan American crewmen and both interviewed by Air Defense Command. Those interview summaries are the only account the archive has. The tier measures sourcing, not truth. What passed below the Constellation, and whether it was one object or two, is not resolved here.
