Background

On January 31, 1958, in Canada, the All-domain Anomaly Resolution Office (AARO) recorded the unidentified-phenomenon case described below. The case is preserved in AARO’s 2024-2025 publications and consolidated annual reports to Congress, declassified or released in the Office of the Director of National Intelligence and Department of Defense reporting cycles.

A cold war-era case investigated under the air force’s project blue book or its predecessors.

The case appears in materials produced or curated by the All-domain Anomaly Resolution Office.

What the document records

Avro Canada designed the Avrocar, a circular aircraft resembling a “flying saucer,” as a supersonic, vertical takeoff and landing fighter-bomber. After Canada withdrew support due to cost, the U.S. Army and USAF took over the project, renaming it “Project Silver Bug,” but it was cancelled in 1961 due to limited lift capacity.

Type of case

The witnesses described the object as disc- or saucer-shaped.

Status

AARO designates unresolved cases as those for which the agency has not concluded the events were anomalous, has not concluded that they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of recent periods include commercial drones, classified test platforms, satellite re-entry, balloon traffic, atmospheric optical phenomena, and astronomical objects.
