what you've found here, if you can.
I know the PR machine for these events was huge, probably bigger than if they even worked or not, with the potsdam events, stalin meetings, domestic pressures, etc. on Truman, who didn't even know about the "Project" untail Roosevelt's death.
I know that Ashford (and Lawrence Johnston) had a lot of clout, and that Ashford was a designer of the triggers for both bombs, and even brought on his assistant to ensure enemy radio signals would not interfere with the triggers. I wouldn't be surprised if he bought 15 of every kind of new photographic gadget for potential PR. Ashford also was responsible for the bomb on boxcar, where it would be deployed, whether they would return with it, go to sea with it, or as what happened, be ready to break the rules and drop it by radar instead of visual if necessary (almost).
So what have you found?
