The Original Radar Plot of Detector Station OpanaRecords of the Joint Committees of Congress (Record Group 128)
The Radar Plot of Detector Station Opana was an exhibit of the Joint Committee. The 22 x 31-inch radar plot was made by Private Joseph L. Lockard at the Opana Radar Station on the morning of December 7, 1941. It indicated a large number of aircraft approaching the island of Oahu. The control officer believed the radar signals announced the approach of American B-17s scheduled for arrival the same day, but the signals actually tracked the first wave of Japanese bombers and torpedo planes that attacked Pearl Harbor.
