A "What If" story set during the Cuban missile crises. An unarmed US jet convinces a Russian freighter, loaded with technicians, to turn back by convincing the captain the pilot will crash-dive into the ship if he doesn't.
As Moore nears his fiftieth combat mission, after which he can return home, the pressure starts to get to him, causing friction with his less experienced crew. His superiors offer him the chance of leave, but he turns them all down. After mission fifty, he volunteers for ten more, so he can help out a new crew.
