I have egg on my face. Sometime back, I set 30,000ft as the altitude where the contrails appear. Now, I want to change that altitude... You guessed it! I can't remember where that setting is, and I can't find it. I went through all the settings, especially where the cloud types, and altitudes can be set, but there's no way I can find it again. (this is bad for my self image, since I did set that once before... bummer

Many thanks to those of you who will reply and save my sanity. :)
