Did they go down from mechanical difficulties or enemy action?
I wonder a bit about Enola Gay's most important sortie in history . . . the vision I have is of a single bomber, unescorted, at super high altitude, beyond what fighters or flak could easily deal with. I wonder why they sent just one plane, if indeed they did.
The Enola Gay went with two additional bombers, but that was it, in terms of the whole route at least.
By the time the Bombs were dropped, the US had total air dominance over Japan, and we had been flying sorties against the main islands for months...and they still refused to surrender.
The reason for this is pretty simple: air dominance is long way from total victory, and the Japanese still had millions of personnel on the mains islands as well as the Korean peninsula and Manchuria.
And that of course is why the Bombs were necessary. We had up to date intel from intercepted transmissions that the Japanese were not going to surrender, and Japanese military officials have stated they were preparing to repel any amphibious assault we might make.
The bloodbath that would have resulted from such an assault would have made Okinawa and Iwo Jima look like a walk in the park. Not to mention the difficulty of lauching the assault, and dubious prospects for its success.
And the only alternative to the Bomb, or amphib assault, would have been leaving the Japanese Imperial military intact. Which doesn't really seem a viable option, more of a postponement.
I apologize for the long windedness, but there is a false narrative perpetuated by the left today that the bombs were dropped "even though the US 'knew'" Japan was going to surrender. That statment is pure drek, and a slander.
The US did know for a fact that Japan had no intention of surrendering (as indicated by diplomatic intercepts), and the proof of that fact is that even AFTER the Bombs were dropped and the Soviets began their assault, and the emperor ordered a surrender, the military attempted a coup to prevent the surrender. If the military was willing to overthrow the emperor to stop the surrender after two atom bombs and the entry of the Soviets into the pacific war, how any sane person could think they would surrender before those events is beyond my understanding.
At any rate, the need for any real escort seemed minimal in the judgement of the command, and they were proved correct.
Also, you noted the high altitude at which the bombs were dropped. This accomplished two purposes. The first was avoiding flak and so forth as you note. The second was to maximize the distance between the plane and the center of the shockwave.
In the WaW documentary about the bomb, Tibbets recounts the experience of the aircraft shuddering from the force of the blast, even at that altitude and distance.
Edited to excise statement about on-board machine guns. They were removed for the Silverplates because of the demands of dropping such huge bombs.
