A possibility I've always pondered is the Allies using kamikaze tactics for the strategic bombing campaign. Instead of sending hundreds of B17's at, say, a ball bearing factory or oil refinery, you send a much smaller number of kamikaze B17's. Replace half the fuel with additional explosives. Prepare everyone but the pilot to bail out during the final approach to target, or maybe not have them along at all. The pilot flies the plane right into the factory. Obviously this was not done, and probably could never have been done, due to cultural factors. But what would have been the result if it had been? I've always believed the results would have been much greater and the casuality list would have been much smaller, particularly in the period before air dominance was acheived. The difference is, at the beginning of the mission, instead of being statistically certain of having maybe 10% killed (but not knowing beforehand who they would be), you would be certain of having a much smaller number killed (but would know which individuals it would be). And based on the success of Japanese Kamikazes in hitting ships, the accuracy would be greatly improved, thus requiring less missions. I've always found this interesting to consider.
