My dad completed a tour in europe and volunteered to follow his bomb group to Okinawa. Even the air corps units were pretty sure that they would have high losses if the invasion went forward and they expected the ground troops to really take a hit. His group dropped warning leaflets on Japan 2 days before the drop and there was a collective sigh of relief when Japan surrendered a week later.
My dad did the same thing, except he was a bit further back in the pipeline. His B-24 outfit in Pantanella, Italy flew its B-24s to Ramey Army Airfield in Puerto Rico. Those who had enough points were mustered out. The remainder of the squadron was set to be reconstituted as a B-29 outfit and sent to the Pacific. Thanks to Col. Tibbets and the 509th Composite Group, the 781st Bomb Squadron never got its B-29s.
