On a serene Sunday morning the residents of Oahu enjoyed the dawning of another gorgeous day in paradise. Unknown to them, three converging formations of military aircraft navigated toward their lush island, homing in on the soothing Hawaiian music playing on Honolulu radio stations KGMB and KGU.
The night before, Lt. Col. Clay Hoppaugh, signal officer for the Hawaiian Air Force, had contacted Welby Edwards, manager of KGMB, and asked that the station remain on all night so a flight of Army Air Corps Boeing B-17 Flying Fortress bombers flying from California could home in on the station’s signal. Actually, it was a less than well-kept secret that whenever the station played music all night, aircraft flew in from the mainland the next morning.
Being nondirectional, however, that same music also drifted into the radio receivers in the operations rooms of Vice Admiral Chuichi Nagumo’s six Japanese aircraft carriers, Akagi, Kaga, Soryu, Hiryu, Shokaku, and Zuikaku, located roughly 300 miles north of Oahu. Nagumo’s task force monitored the station throughout the night for any hint of a military alert on Oahu, and at approximately 7 am on Sunday Lt. Cmdr. Mitsuo Fuchida, leading his formation toward Oahu, also tuned in KGMB to guide his 183 aircraft to their destination. While Fuchida homed in on KGMB’s signal, 18 U.S. Navy Douglas SBD Dauntless dive bombers took off from the aircraft carrier Enterprise 200 miles west of Oahu and tuned in radio station KGU to get some homing practice of their own. Shortly after 8 am, the three converging formations, each tracking inbound on the same innocent radio beams, collided in brutal and deadly aerial combat that would plunge the United States into World War II. The date was December 7, 1941.
