Project Blue Book Case #2384. On February 3, 1953, an unidentified object was reported over Iceland — the third Blue Book unknown from this mid-Atlantic NATO island (joining Cases #3699 and #3523 from Keflavik). Iceland's accumulation of three unknowns reinforced its status as a persistent problem location along the GIUK gap — the critical North Atlantic passage that NATO monitored for Soviet naval movements.
February in Iceland brought near-total darkness, extreme cold, and the aurora borealis — conditions that DEW Line and NATO personnel were specifically trained to distinguish from genuine aerial contacts. The case was classified "Unknown."
