Of course. The military says to a company like Grumman or Lockheed, "we need an airplane that does this, this, this, this, and that without being seen by radar". Lockheed designs a plane that can do it. If the military came to be and said the same, all I'd be able to tell them is that I could design a plane that can fly, turn, and land. Well, I could also install an AM/FM radio on the instrument panel, heheheh!

For some reason, everyone has a difficult time understanding that it's lift and balance that get the plane to take off and stay airborne. Same for a Cessna as it is for a 747 as it is for an F-117 as it is for a B-1. Where the aerodynamics makes itself evident is in the speed and flight characteristics. But again, what makes all these planes simply "fly" is identical for them all.

Case in point: we see CAP-231s and F-15s perform barrel rolls. Well, did anyone here know that a Boeing 707 has done the same? Just not as snappy as the CAP or the F-15.

Lastly, I'm 99% sure that there's an increase in pressure under the airfoil, combined with a decreased pressure. Try this:

drive in your car at 60mph, and stick your hand out the window with your palm facing down, but angled upwards at about, oh, 10 degrees. You'll feel a force on your palm. That's pressure (divided by the area of your palm).
