What is the greatest military plane of all time?

SR-71 is definitely in a cl by itself and one of my favorites as well. I would have to say though, given the longevity and reliability of this plane, it would have to be the B 52 bomber. I don't think there's any other plane in the world that has had it's success and longevity. The military did a great thing by purchasing these planes and they definitely got their moneys worth and then some. That makes it the greatest military plane of all time.
