Regarding the shape of the Phantoms wings, with the 'bend' at the wing tip. Years ago I worked in St. Louis and had a mate who worked for McD. who told me a tale he had been told by one of the old engineers as to how it had come about.
The story was they were doing some wind tunnel tests on the aircraft and while they were carrying the model they were using into the wind-tunnel it got dropped and the wing tip got bent. After some discussion they decided that this shouldn't affect the tests they were doing (which were on the nose area, forward of the damage) so they would carry on with the tests. When the tunnel was switched on though they found the model 'flew' asymetrically, with more lift on the bent wing. Further experimentation showed the bent wing was more efficient and the whole aircraft ended up with the final shape.
Always suspected that one should have 'Urban Myth' stamped on it in large letters but, given that there was a lot less in the way of design aids (no computers to speak of for instance) back then it could be true.
