Narrator: Apparently aloof from the rest of World War II, the solitary 509th, still unaware of its own purpose, carries on its puzzling training schedule. Their orders: practice runs to nearby islands. Then their own private missions to Japan, always above thirty thousand feet, always alone or in threes, always to drop just one bomb. Each time they must return to Tinian to face the ridicule of their fellow flyers. A poem is written in their dubious honor.
