OVA by MADHOUSE — Fall 1993, 3 episodes, Finished.
1. Slipstream About a Luftwaffe pilot who must choose between his duty to his country: to guard a bomber loaded with Germany's final hope of victory... the world's first atomic bomb... or his duty to the world: to let it fall in flames to enemy Spitfires and be a footnote in history. Of course, things are complicated by the plane's other cargo... the woman he loves. 2. Sonic Boom Squadron Near the end of the war, Japan has implemented a new weapon -- a human-piloted rocket-propelled flying bomb.
