John Hafen  replied:   I agree with Tom and would add that Money is a derivative of “kitchen clearance.”  Therefore, it is actually “kitchen clearance” that is the most important force that keeps a wing flying.

 John, I didn't do well in series and differential equations, so I'm not sure about this derivative "thing" but I think you are on to the correct answer.  A recent attempt to make a wing fly:

Lancair 7VG:    "Kitchen, Lancair 7VG, IFR, Palomar California, Hangar Bravo, ready to taxi with Tango."
Kitchen:  "Lancair 7VG, clearance hung up at Mercedes dealership, try calling back next week."
I think this derivative you mentioned could be the "Coranda" effect.  I better "co ran da" to the Mercedes dealership if I want that wing to fly.
