As much as I can remember Okay, it has planes with no wings. The main characters are a boy and a girl, their dad died and left them a plane. They race it at the beginning of the anime then as time goes on they become messengers then start fighting in a war. The guy is pilot and the girl is rio. At the end the girl is like "I can't take the plane up to fight." It's kind of like an anime that is set back in what seems to be the 1930's with futuristic sci/fi technology.
