Well shit. It's such a shame all those engineers spend so many years studying when all they need is basic knowledge.
And all that money going to R&D. Complete and utter waste. Don't need R&D when all the knowledge to build a car is already there. You learn it in 10th grade shop class.
You should build your own plane with your basic knowledge (All you need is more lift than gravity and more thrust than drag!) and post the video to prove us all wrong! Don't worry about stability and control theories, as long as the plane flies it's not important whether it does a nose dive without input or departs immediately. Don't worry about when/where you want to trip the turbulent boundary layer. You've already figured it out with brute force with your more thrust than drag knowledge! Don't worry about which NACA airfoil you should use. You'd need to use Navier-Stokes to find out how much lift is created over iterative portions of the wing. So that's out because it uses gravitation. Theories be damned! We can do this without them! Don't worry about power transmission. Again, we've figured this out with our more thrust than drag knowledge. Control surfaces? I say yes! Where? Somewhere! How do we counter torque moments? With anti-torquers! How do we make sure our plane will fly? Put it in a wind tunnel, and if it doesn't explode, wa la! Plane.
Come now, Steel. Hasn't Huggies convinced you yet that theories are just wild assed guesses. Surely all that R&D is actually just smoke and mirrors to drive prices up!
