Pearl Harbor was attacked by 353 Japanese fighters, bombers and torpedo planes. Japan had planned this attack for a year and a half, with the aircraft crews training for fourteen hours a day. The first wave of the attack arrived on December 7, 1941 at about 7:49 AM, Hawaiian time. The first bombs were dropped on Wheeler and Ford Island at 7:55 a.m. The plan of attack incorporated lessons learned from study of the Fleet Air Arm attack against the Italian fleet at Taranto in November 1940.
