-What happens is that vortices are engendered. Wing design is all about getting them past the control sections (the major problem to aircraft design in the 1940's.)

 It is a convention in fluid dynamics that the flow always comes from the left. Nobody working in this field would ever draw a picture with the flow coming from the right side. So this is a hint by its own that the image may be wrong.

	My high school math teacher said there were three ways for a teacher to say "I don't know" -- "I don't know", "It's beyond the scope of the course", and "You wouldn't understand it if I told you." So, whenever we asked a question like the one in the comic, he'd say "It's beyond the scope of the course, and you wouldn't understand it if I told you anyway! Dumb kids!" We loved that guy.
