Arguably one of the most audacious missions - land/sea/air - in all of WW2. Amazing training and even more so, courage of the crews.
I agree, though it is a shame that there was no real plan for the post-Tokyo part of the raid. Many planes simply ran out of fuel and the crews had to bail out (some in hostile territory).
For audacity it definitely ranks up there with the German airborne assault on Crete and the Japanese attack on Singapore; both took high losses for incredible gains. In Singapore the Japanese were so depleted/outnumered and their supply lines so stretched they thought the British expected them to surrender (with good reason), and were shocked that the British themselves were surrendering.
