I was just setting up on AR4373 when this jet flew over. The funny thing is that the contrail is nearly transparent. All the others I have captured are like black smoke trails. (the fuzzy shadow is a tree branch – Sun is still pretty low at 57N)

UPDATE: Closer inspection in slomo shows it is actually a plane with propellors which maybe explains the mystery. See video below.
