It doesn't? I thought the lines approached the airplane at an angle (say, 3 degrees, being generous), not square on.

Wolfgang Nieuwkamp:
Brett, you convinced me after making a principle drawing:
For clarity the line (red) sag is exaggerated.

Serge_Krauss:
Centrifugal force and line tension are not the same. For a certain mass flying in a certain-radius circle at a certain speed, the centrifugal force is always the same. Aero forces change line tension.
Howard Rush:
Ain’t no D line y, except for the tiny amount when you’re upwind or downwind.
Howard Rush:
Now that I think about it, there would be a radial force on the line from the air blowing on it. It wouldn't be drag, which is defined to be in the direction that the airstream is blowing on something, but a lift or side force component. One could integrate that from the handle to the airplane. I doubt if it would amount to much. I could see what Dr. Hoerner has to say and calculate the net force. I guess, but I don't plan to.
