Original Note:

37K feet is the troposphere, SAI would happen at ~65K feet. Planes within close proximity, like the video, would have to be seperated by at least 1000ft, usually 2000ft, which is enough to cross the contrail formation threshold. Therefore the video shows contrails. https://skybrary.aero/articles/separation-standards https://scied.ucar.edu/image/multiple-contrails
