I was reading an article the other night on the downing of Yamamoto re accurate navigation..
It was Palm Sunday, April 18, 1943. But since there were no religious holidays on Guadalcanal, we took off at 7:15 am, joined in formation, and left the island at 7:30 am, just two hours and five minutes before the planned interception. It was an uneventful flight but a hot one, at from 10 to 50 feet above the water all the way. Some of the pilots counted sharks. One counted pieces of driftwood. I don’t remember doing anything but sweating. Mitchell said he may have dozed off on a couple of occasions but received a light tap from “The Man Upstairs” to keep him awake.
Mitchell kept us on course flying the five legs by compass, time, and airspeed only. As we turned into the coast of Bougainville and started to gain altitude, after more than two hours of complete radio silence, 1st Lt. Douglas S. Canning––Old Eagle Eyes–– uttered a subdued “Bogeys! Eleven o’clock, high!” It was 9:35 am. The admiral was precisely on schedule, and so were we. It was almost as if the affair had been prearranged with the mutual consent of friend and foe. Two Betty bombers were at 4,000 feet with six Zeros at about 1,500 feet higher, above and just behind the bombers in a “V” formation of three planes on each side of the bombers.
