Have you ever seen those short strands of yarn some glider pilots tape to
the front of their canopies? The goal is to keep the strand straight down

equal airflow on either side of the hull.



Actually, yes, I have a comm rating in gliders, but that string is on
the wind screen,
not sure if it reflects the forces on the vertical stab. I don't know,
maybe someone does.
