My nomination is:
The F-104 Starfighter.
Despite being possibly the coolest-looking plane in the universe, I hate it because:
1) The wing has a tiny aspect ratio and obscene wing loading.
2) As a result of that, it turns like a fast-moving brick and lands at dangerously high speeds.
3) As another result of that, the trailing vortices developed at the wingtips are very strong indeed. Coupled with the low aspect ratio and limited breadth of the wings, this gives a very inefficient wing design, which coupled with its already limited supply of fuel make it more short-legged than a duck.
4) The trailing vortices are so strong that other F 104s have to keep their distance when flying behind it, even on takeoff.... or they may crash.
5) The T-tail..... oh, the accursed T-tail. This is the most stupid thing in the world to put on a fighter. When that aircraft pulls any significant angle of attack, the breakaway turbulent airflow from the upper wings will cover the elevators, thus causing the pilot to lose all pitch control.
6) The fuel efficiency was so terrible that the stupid amount of external tanks shown above was necessary to keep it going for any distance at all.
7) It has one engine and one engine only. If this flames out, you might as well eject because it glides like a brick.
8 ) The design was so hopelessly bad that Lockheed had to bribe nations and political figures to accept it!!
Which is why, ladies and gentlemen, I hate the F-104 Starfighter.
You may show me designs which piss you off now.
