I found another site with pictures of a contrail nearly identical to the one I photographed in Meadow Valley. This one was over Reading, England, I think. I wonder if these things can be caused by certain specific environmental conditions interacting with the certain specific aerodynamic characteristics of a the exhaust of a particular type of airplane, possibly a civilian airliner? So many questions, so little time.
