Airfoil. ASCII.

Read on HN about the http://xkcd.com/803/ with the comment "What's the correct answer ?"

I think it is this:

                                                


^ counterforce
| lifts the plane
|
+
/--- <-- this is a wing
spits hot pollutants <===[engine]===> counterforce /---
pushes /---
forward /---
/--- +---- <=== air hits
| this direction
|
|
v air
bounces down




The drawing is imprecise. I welcome you to spot the places where it is.

But it should be correct in principle.
