No, I don't know what you mean and I've been coming here for 5
years. In any case the same could be said of snow, which often seems
"to take the reason prisoner". Contrails must have an effect on the
radiation budget, being at times so widespread. 4 oktas of
anthropogenic cirrus is not negligible, and worth discussing.
