"In order for a wing to produce lift it has to be at a positive angle to the airflow. The positive angle to the airflow forces an increased amount of air beneath the wing."

In practice very little downward acceleration occurs beneath most common wings, most of it happens above. The words that this replaces give a simple factual statement of what happens.

"By forcing air beneath the wing lift is generated causing the aircraft to rise. This effect of lift is in direct accordance with the third law of Newtonian physical principles."

All motion (below the region of the speed of light) complies with Newtonian physical principles; it is therefore redundant to say so here. It is also argumentative as the entire edit attempts to put forward the false argument that Momentum effects are independent of Pressure effects. You cannot have one without the other.

" This action of forcing air beneath the wing results in a dramatically decreased amount of drag and resistance acting upon the wing and thus the aircraft as a whole."

What does this mean? The downward acceleration of the air creates drag.

" As a result aircraft and other wings that react with fluids are capable of being formed that are able to create a significantly high enough degree of lift that the wing itself does not necessarily need to be particularly wide."

What does this mean? Particularly wider than what? As we are not being numerate this statement is entirely redundant.

" In short, aircraft wings generate lift by forcing air downward and causing an amount of lift that is in direct reaction to the amount of air that is forced beneath the wing. This allows wings to (once a certain threshold of forward velocity is reached) to essentially hover on a cushion of air that is being continually forced down beneath the wing itself."

Wings do not hover, the word "cushion" needs to be defined, the air is not forced down "beneath the wing". The air is not permanently moved downwards - ie there is no permanent displacement of the air downwards so that the atmosphere is continually getting more dense and lower with the passage of every aircraft?

" No form of vacume or pressure differential is required in order to generate most forms of lift, despite what has previously been suggested."

Pressure differences are essential and "what has previously suggested" does not refer to any passage in the article as edited.

" Lift is entirely a result of the interaction of basic Newtonian physical principles regarding how physical reactions occur that are directly opposite to initial actions (Newton's third law)."

The only way a fluid can (excluding friction) be accelerated is by a pressure gradient. The only way a fluid can (excluding friction) exert a force on a solid is via pressure differences.

Both happen, accelerations of air and pressure differences - they are, as the article already states, totally interdependent.
