Original Note:
This video shows an aerodynamic contrail from an Air Canada flight, filmed over Zurich on 19 June 2023: https://twitter.com/TakeThatClouds/status/1673977680780308481?s=20 Aerodynamic contrails form due to the pressure drop above the aircraft wing, which makes water vapour condense. They often exhibit this start-stop behaviour, as seen here: https://www.youtube.com/watch?v=P3-IWfgsEeM
