Douglas Bader's Spitfire lacks drama. Warspite should be more popular too, she played a critical role a lot of theaters during the war. Richthofens Red Triplane (no matter which one) is far more popular than his Albatros planes because he died in it. Bismarck didn't survive her maiden journey although declared as unsinkable - the Titanic of all warships. Enola Gay or Little Boy are hard to beat.
