Just an interesting fact...

The sweep of the wings of the F-117 was based on a paper airplane. The prototype, have blue, had a sweep angle of about 72 degrees. It was decided to decrease the sweep and the designers looked towards the great paper airplane. When paper is folded twice, the resulting angle is 67.5 degrees. It was then rounded to 67 degrees. So, I guess there is a place for simplification....

But then getting it to fly and maintain it's stealthiness wasn't quite that simple. I don't think a paper airplane could do much here.

There is another thread on the Spitfire wing I've run into. The funny thing here is that the wing was mainly designed that way to fit the guns inside of the wing outside of the prop arc.

Angular momentum......now that's dynamics, not aerodynamics. I think we might have to start a new forum.

T28, dude you nailed it. More power. A barn door will fly (and loop) if it has enough power. Who cares about efficient lifting surfaces. I've seen it done. It just didn't fly all that well.

I'm bored, just having fun, no offense intended. I'm a fence sitter I guess.
