Sixth Blue Book unknown at Goose Bay Arctic interceptor base, Labrador (1952)

Project Blue Book Case #1308. On June 19, 1952, an unidentified object was observed at Goose Bay — the sixth Blue Book unknown from this critical Arctic defense base. Six cases across eight years made Goose Bay the undisputed record-holder for repeat unknowns at any single military installation in the entire Blue Book database. The Arctic base whose mission was to identify everything in the sky had now failed six times. The case was classified "Unknown."
