Hello, internet! Did you get your morning cartoons? :)
Wingtip vortices are a result of the finite length of a wing. Airplanes generate lift by having low-pressure air travelling over the top of the wing and higher pressure air along the bottom. If the wing were infinite, the two flows would remain separate. Instead, the high-pressure air from under the wing sneaks around the wingtip to reach the lower pressure region. This creates the vorticity that trails behind the aircraft. I was first introduced to the concept of wingtip vortices in my junior year during introductory fluid dynamics. As I recall, the concept was utterly bizarre and so difficult to wrap our heads around that everyone, including the TA, had trouble figuring out which way the vortices were supposed to spin. A few good photos and videos would have helped, I’m sure. (Photo credits: U.S. Coast Guard, S. Morris, Nat. Geo/BBC2)
I’m really glad I explained this right to the 4-H aerospace camp kids.
I made a mashup of “Whip My Hair” and “I Write Sins Not Tragedies” …

i got a few letters at first but then i didn’t hear for months. finally i got a letter that made no sense. she talked about things that never happened, jokes that we never.. it was code. it just said… “they’re hurting us. get me out.”
