My late father (who instilled in me the love of trains) was stationed on Tinian island, he was a mechanic for the 505th bombardment group. He told me lots of stories of B-29's crash landing and the time him and his buddies happened upon a surrendering Japanese soldier. The most interesting story though was one of a group of a small group of Super-fortresses that was off limits to nearly everybody.
They were different, didn't have any guns and they were real shiny polished aluminum. One allegedly had a round the clock US Marine guard around it and they joked that FDR was inside sleeping. One morning they woke up and it was gone - it was the Enola Gay! The rest is history.
