I am well aware that planes like the B2 bomber for example are aerodynamically unstable air foils which require a computer to make constant corrections to its trim configuration to keep it airborn and flying smoothly. That does not change the fact that what keeps it in the air in the first place are aerodynamic principles and engines. In this case as I have just pointed out in another posting, the programmer writes software at the direction of and to the satisfaction of the aerodynamics design engineer whose mathematical models define what the programmer must achieve. Left to his own devices to solve the problem without the aerodynamics engineer to supply his expertise, the plane would never leave the ground. The successful implimentation is therefore the result of aerodynamic engineering with assistance from another discipline, computer programming. The programmer actually engineered nothing.BTW, this points out another distinction between computer programming on the one hand and engineering and pure and applied mathematics on the other. The engineer and mathematician are confronted with open ended problems which do not start off with the knowledge that a solution exists. Programmers can be certain however that they can successfully write a program to solve any problem once it is defined. It only becomes a matter of how much memory, how many instructions, and how much time and cost it takes to develop the solution.
