Obviously @alpha has done an amazing job with his extensive list of aircraft, but I was watching videos on YouTube (who doesn't do that, right?) and happened to come across a very nice Airbus A350, which I didn't know about. The plane is only 4 years old, and looks very sharp, I might add.
Of course, this plane is competition to the Boeing 787, which means we'd have to look into slowly bringing in the larger aircraft, but I felt the Dreamliner and the A350 were pretty sharp with the blended winglets, and in the A350's case, the all-black windows with rounded edges on the cockpit! Not bad, I don't think. Sorry if this seems redundant, but I wanted to suggest at least those 2 aircraft.
Oh and Psst... Don't forget the CS100 LOL
