I would add in second place Skunkworks and the A12, which is the perfection of aviation technology in my opinion. It's just such an insane piece of technology, in every part you take a look at it gets more and more absurd of what's in that plane. And if you build an airplane so absurdly advanced that 70+ years later people still think it was aliens that built it, you've set your mark in the history books. Third place in my heart takes the Rutan Voyager [2] which essentially pushed its efficiency so hard that it coincidentally invented the design for modern delivery drones.
