“Before the first streaks of light at dawn on December 7, 275 miles north of Oahu, the six (Japanese) carriers of the Striking Force turned into the southeast wind. Pounding into heavy swells at high speed, the carriers pitched severely with thunderous impact. The wind, surging seas, and roar of warming aircraft engines made communications possible only by hand signals and handheld signal lamps. Salt spray reached the high flight decks, and Commander Fuchida, the group leader, was very concerned about the conditions for launching planes. If this had been a training exercise the launch might have been delayed until conditions improved. However, this was not an exercise, and there would be no delay.”
