      4. The mission almost went completely sideways. The main target, Kokura, was obscured by smoke and/or clouds, for reasons that have never been really definitively determined.http://blog.nuclearsecrecy.com/2014/08/22/luck-kokura/ …

      5. After wasting a lot of time, first trying to rendezvous with an observer plane after flying through a storm, and also over Kokura, Bockscar went to Nagasaki with barely enough fuel left. But Nagasaki was also obscured by clouds.

      6. With the alternative being to drop the bomb without really seeing the target, or drop it in the ocean (because they didn't have enough fuel to fly it back), they opted to countermand their main orders about visual bombing and drop it based on radar.

      7. The bombardier would later claim there was a miraculous hole in the clouds... but observers even at the time would note that they missed their target by a substantial margin, the same margin you'd get if it was radar-bombed.pic.twitter.com/4382f2Avy9

      8. The bomb actually ended up detonating over one of the most civilian areas of Nagasaki, and (ironically) one of the most Christian areas of Japan. The USAAF's own maps indicate that almost everything near GZ was civilian: houses, schools, hospitals.pic.twitter.com/sIpsBOyMqZ

      9. It is essentially coincidental that two factories that produced munitions happened to be at the northern and southern fringes of the blast zone. The geography of the city also meant that, unlike Hiroshima, it was still functional (in the large "lower" half) after the bombing.

      10. There were more mishaps and near-misses than I could even fit into my New Yorker article. Here's one of my favorites: that time in which the Fat Man bomb appeared to indicate, mid-flight, that it was armed and ready to detonate. From John Coster-Mullen's book.pic.twitter.com/EqEmZR7CGf

      11. The bomb itself was christened with the acronym JANCFU: Joint Army-Navy-Civilian F*** Up. I think this was about as prophetic as one might imagine. The Nagasaki bombing run was as clear an indication that the nuclear age would be full of unpredictable mishaps and risks.pic.twitter.com/ikvtyAXKJ8

      12. I'll just finish with my conclusion paragraph in my New Yorker piece on Nagasaki — which, as an aside, is still perhaps my favorite piece of writing I've ever done. FIN. https://www.newyorker.com/tech/elements/nagasaki-the-last-bomb …pic.twitter.com/c2pMyyXz11

      These bombs finally convinced a suicidal Japan (that committed heinous war crimes, and was never, ever going to stop) to halt it's attempt at world domination like nothing else could and saved many 1000's of allied lives. Completely justified. No apologies. #Nagasaki #NagasakiDaypic.twitter.com/5cfN9TxEfv

      There is no evidence that the Nagasaki bombing played any actual role in the decision to surrender, as an aside. Hiroshima — maybe. But most historians agree Nagasaki didn't affect things in any significant way, and was probably unnecessary.

          And the "was never going to stop" bit is patently false. The Japanese high command was searching for ways to end the war. I don't want to underrepresent the complexity of that. But you've got totally wrong ideas floating around your head. If you want a reading list, just ask.

          Lastly: I'm not sure who you're addressing with the "no apologies," but that's not my aim here. My aim is for people to understand what it was, beyond the myths. The Nagasaki run was a mishap-filled slaughter of non-combatants, and not part of any coordinate strategy.

          This is true whether you think it was ultimately justified or not, which is a separate question entirely, and informed people can come to different conclusions on that. But you've got to get the facts straight first, or else you're just repeating someone's propaganda.

          How can you possibly believe the combination of 2 atomic bombs, but specifically the bomb dropped on #Nagasaki (Aug. 09. 1945) had no "actual role in the decision to surrender", when that decision was announced on August 15, less than a week later?

          What I'm picking up from these exchanges is, you haven't actually read anything about Japan's surrender. I would be happy to tell you (and others) about it. But I first want to make sure that your goal here is to become less ignorant. Is that fair? Or are you just trolling?

          I'm not trolling. I just got done with 5 days of research. Your claim "There is no evidence that the #Nagasaki bombing played any actual role in the decision to surrender" demands that I try to prove a negative. It is you that needs to prove they didn't play a role.

          Quick aside: 5 days of research is a good start! But just for context, I have a PhD in the history of science, and my job is as a historian of nuclear weapons. I'm not appealing to expertise here, but just giving some context to my answers. I'll come back to Nagasaki in a moment.

          I didn't say 5 days was all I'd achieved over the last few decades. But okay Dr., as I said, I'm willing to look at your evidence that the Japanese high command was willing to surrender before Hiroshima as you claimed. Please send that.

          The US high command didn't receive the declaration of surrender from Japan until August 15th, 1945 (more than a week after the second bomb...).
