The illusion here is that it appears to be a chemtrail left by a single aircraft flying a circuit. Actually, it's 5 planes (count the turns at left) flying in a race track pattern. Each aerial dispersal platform has a unique turning circle, as determined by factors like pilot comfort to G forces, wing loading and speed. The photo is from the chemtrail equivalent to the Reno Air Races: the Chemtrail Olympics. This was the start of the 2018 1,000 km Chemtrail Challenge. Pilots were tested on a variety of skills, including formation flying, pre-school overflights and artistic use of the on/off switch. In 2018, notable contestants included Senior Chemtrail Pilot Bob and (winner) Captain Carl.😉😎
