The A-26 was the plane of the 319th Bombing Group, who had been in Europe until early 1945, when it returned to the states to eventually become part of the Okinawa campaign. The plane itself doesn't seem to have made many friends during its short time in the air, and in any case Nagasaki was about to receive a more effective bomb, 11 days from now.
So on to two other short topics. First, I studied the weather map fairly closely, and discovered, not to my surprise, that the weather wasn't that different from any other late July between then and now, and neither were the temperatures different. Global warming advocates would not be pleased.
Second, a Google search of "United Negro News Service" brought up no hits. I have to assume the idea didn't go anywhere, presumably because of the integration that occurred in many business sectors in the late 1940s and 50s.
But you can take it to the bank that in a few months NOAA will proclaim this the hottest year on record.
