Wings can produce {{w|Lift (force)|lift}}.{{Citation needed}}

Randall previously dealt with explanations of wing lift in [[803: Airfoil]].

There are three actual reasons why airplane wings produce lift:
* {{w|Bernoulli's principle}} (which is the most frequently cited)
* The airplane wing is angled up at the front so that air hits the bottom and is pushed downwards.
* {{w|Coandă effect}} (The top is curved, so air going over the wing must curve downwards in order to avoid creating a vacuum above the back of the wing, and by Newton's third law, this results in an upwards force on the wing.)
The comic references all three of these reasons. Airflow splitting references Bernoulli's principle, while the air at the bottom being scared and fleeing downwards is similar to the actual effect, which is caused by air hitting the angled bottom of the wing. The air going over the top curving down references the Coandă effect, claiming that this effect is instead caused by the top-flow of air itself noticing the bottom side of the wing going down to investigate why the bottom-flow had fled. The mention of Newton's third law is indeed correct, even if the movement of the air is for the wrong reasons. In the title text, it additionally suggests that the top-flow henceforth glimpses the printed skulls, causing it to also chaotically flee, generating a wing's classic turbulant wake.

[Caption at the top of the panel:] How a wing produces lift

[A diagram of the cross-section of a plane wing. It  is large and rounded on the left end and flat on the bottom while the top curves down to meet it at a sharp point. There are many small arrows indicating the flow of wind, as well as captions.]

[The arrows come from the left of the panel, point towards the wing, and then half begin to go over and half begin to go under. A caption in the middle of this flow reads:] Airflow splits around the top and bottom of the wing

[A circle underneath the diagram is connected to an arrow which points to the underside of the wing. A repeating pattern of small black (simplified) skulls fills the circle and arrow. The caption to the right of this is:] Spooky skulls microprinted on the bottom of the wing frighten the air, which flees away downward

[The arrows begin to curve downwards after this caption, and are joined by the top arrows which have also begun to curve downward. In these arrows is a caption:] Top air goes to see what's wrong

[Both streams of arrows have joined and are pointing to the bottom right of the panel. In front of them is a caption:] By Newton's third law, downward deflection of air pushes wing upward
