Project Blue Book Case #969. On September 13, 1951, an unidentified object was observed at Goose Bay Air Force Base, Labrador — the third Blue Book unknown from this critical Arctic defense installation (joining Cases #2555 from 1953 and #3969 from 1956). Goose Bay's accumulation of three unknowns across five years made it one of the most persistent problem locations in the entire Blue Book record.
The Arctic interceptor base, designed to stop Soviet bombers on the polar route, could not identify objects in its own airspace on three separate occasions — a deeply troubling record for a facility whose sole mission was aerial identification and interception.
September 1951 was during the Korean War and the Fort Monmouth radar events that would lead to Blue Book's creation. The case was classified "Unknown."
