All but one of the B-17s was lined up on the field and the fighters were just getting ready to take off. After the warning of the Pearl Harbor attack, and after the loss of several valuable hours because of bad weather, the Japanese pilots did not expect to find so rich a harvest waiting for them. But they did not question their good fortune. The first flight of Japanese planes consisted of twenty-seven twin-engine bombers. They come over the unprotected field in a V-formation at a height estimated at 22,000 to 25,000 feet, dropping their bombs on the aircraft and buildings below, just as the air raid warning sounded. As at Pearl Harbor, the Japanese archived complete tactical surprise.

The first flight was followed immediately by a similar formation which remained over the field for fifteen minutes. The planes in this formation, as in the first, accomplished their mission almost entirely without molestation. American antiaircraft shells exploded from 2,000 to 4,000 feet short of the targets. After the second formation of bombers, came thirty-four Zeros--which the Americans believed were carrier based--to deliver the final blow with their low-level strafing attacks on the grounded B-17s, and on the P-40s with their full gasoline tanks. This attack lasted for more than an hour.
