One loose end that perhaps someone could pin down would be the relationship between regular pilots and kamikazes. There had been scattered suicide attacks earlier in the war before the kamikaze program got rolling; some of these were pilots with crippled planes trying to make it count, and some were apparently prompted by an excess of bushido. My impression, however, is that for the most part, the kamikazes were mostly new pilots, sketchily trained. From a command perspective, I would think Japan would have tried to conserve its dwindling pool of good pilots and would not have thrown them away on kamikaze runs.
They did have the BAKA bomb.
