Original Note:
On June 19, 2023, an Air Canada flight from Athens to Montreal passed over Zurich, creating an aerodynamic contrail in the humid sky. Contrails form under specific conditions and stop abruptly when the plane drops below the critical humidity level. https://elib.dlr.de/58314/1/i1520-0469-66-2-227.pdf https://journals.ametsoc.org/view/journals/atsc/66/2/2008jas2767.1.xml https://ui.adsabs.harvard.edu/abs/2013ACP....1310847G/abstract
