    Locating the engine, especially the mount in the forward aspect of the wing...

    Recall from Major Kong's piece stating that "center of gravity must be forward of center of pressure".

    Between those two load factors, the entire weight of the airplane is in the forward third of the wing (approximate value).

    Conveniently, that is where the wing is thickest and built like the proverbial brick man-cave...
    The height of the wing in that region is tallest and most resistant to all loads and distortions.
    To quickly understand this, imagine if a wing had to bear the strength at the thin trailing edge; developing a structural strength on a razor's edge would be impossible.

    Locating the engine mid-wing would be aerodynamically preferred.
    However, doing a "fix", "on the ramp", in a buried engine rather than in a stand-off nacelle enclosed engine has to be considered.

    Enagaged activism wins elections. 100 million words on liberal/progressive websites gets beat by one new GOP voter casting their vote.
