I love the whole thing. The 757 and 727 are two of the most beautiful aircraft to ever grace the skies.
Without trying to sound like a total geek (too late lol

), I love the long slender design on the 757, the wing shape, and the overall rugged look to the plane. It looks like a tough plane, yet at the same time graceful.
I love the way that the bogies tilt on approach. The 767's wheel bogies tilt forwards. The 757s, however, tilt backwards, which almost makes the plane look hawk-like on approach.
The nose....the best nose in the industry. I know it sounds weird to say a plane has a nice nose, but what is the first thing you see of that plane when you meet it at the gate? The nose. The shape of the nose is of course one of the most aerodynamically important considerations as well. The shape of the nose and wings directly affect drag and speeds at which the aircraft can fly. The 767's short, stubby nose implies a slow speed for that aircraft. While the 757's nose, being thinner and more elongated, indicates a higher speed for that aircraft. In many cases this is true. The concorde's needle-nose screams "supersonic aircraft".
But one of the often overlooked features which has always stood out on the 757, are the size of the engines. Granted, the 757's engines aren't as big as, say, a 777s, but compared with the fuselage width of the plane, those engines look huge. Especially from the right angle. The 757-200 is overpowered and for a reason...Boeing always planned to stretch the design while still using the same engines.
So what you have is a tough aircraft with clean lines and a beautiful sleek appearance, which can crank out some serious power from its engines which are quite huge viewed from the ground compared to the plane. It's an aircraft that commands attention at any airport just by its looks. And one of the most beautiful designs Boeing ever came up with. The 757 has more personality in its left main landing gear than any 737-400 out there today.
Now, that's just the 757, and the 757 is my second favourite aircraft to the 727. Don't even get me started on the 727!
