Lookin at hydro's naucean post I thought of something.
BTW those wings were filled with hot air they were not just soildi wings, so it was a mixture of a bi-plane and airship. Thats how it stayed up in the air. If it did not have those it would not fly very well due to the propeller on the back. However for airships propells on the back work just fine.
Yup, I know. I thought it was cool, but quite obviously it'd fly very differently from a normal human fighter plane: possibly softer motion, harder to controll but far more flowey, not to mention that it could travel at a very wide range of speeds that a plane couldn't.
See, my main gripe is not just that anything could fly - it's just everything would fly
the same way to within a few degrees of customisation.
With mine, although harder to do, it'd be able to create amasingly customised machines - anything from a working spitfire to something that uses helecoptor blades to lift and pulse-fusion engines to propell it at high speeds in any direction.
The dynamics wouldn't have to be perfect, but the body itself would need to be physics controlled. then you just add stuff to it to make it fly how you want.
heck, you could probably make something that spins to fly....
