Original Radar Plot of Detector Station Opana, Oahu, Hawaii, December 7, 1941

At 7:20 a.m. on December 7, 1941, two novice radar operators detected aircraft approaching Oahu. Their control officer believed the signals tracked American B-17s, but by 7:55 a.m., the first wave of Japanese bombers attacked Pearl Harbor. A 1945 Congressional investigation of the surprise attack examined this radar plot.
