The Valkyrie

Red Skull's plan for domination began with a super bomber. This plane was a hybrid of prop planes and stealth bombers. It could launch Hydra planes from an internal hanger. When Red Skull finally flew the plane, it would be the only time he would ever do so. After Red Skull's defeat, the plane was still targeting America, so the Captain had no choice but to crash it in the Arctic. The plane was dicovered years later by S.H.I.E.L.D., in pieces.
