The explanations are textbook, but they leave out an important detail. Wings (mostly) generate lift from a difference in pressure above and below the wing while in flight. The reduced pressure above the wing basically 'sucks' it upwards. The result of this pressure difference creates a massive downward force behind the wing, which is usually what's referenced when explaining these things. Here's a paper that explains it a bit more: http://www.pilotfriend.com/training/flight_training/aero/lift.htm http://www.pilotfriend.com/training/flight_training/aero/lif...
