The perk of an airline pilot. Yesterday over here.
Impressive, they grow horns and legs now but no need to worry, it’s just ISOL CB in TAF

A jet plane that did a 720 (two 360ies) to the left with decreasing air speed while doing so. He started from the right of the picture flying to the left of the picture at the far end of the pattern and due to increased AoA during turn the pressure difference resulted in contrails.
