I see them and just the last two days I've seen the infamous white plane from a distance. I see them mostly in the alate afternoon, over the state in which I live. (FL) Just recently, I notice how they are dissolving, almost like drops from the streaks in the sky. Generally then it clouds up sometimes,shortly thereafter. I would be interested in knowing if anyone else has seen them, and what do you suppose they're for?
I spend quite a bit of time outside walking (my chosen exercise)sometimes they're there in the mid-morning hours as well.
