I saw the “capture” of the banners at the small flying field where I used to keep my Cessna 172 many years ago. It is pretty cool and if the old gray cells serve me correctly it took several tries to capture the banner. I suspect it is a bit of pucker time for the student pilots (quite a few student pilots used it to gain hours on the cheap).
Bottom image was “my ride” in my younger days. With me is my grandson who loved to go up and look for trains; he is now 24.
