I think there's a lot that can be learned from Wikipedia and Google. Though, ultimately I still dunno what is in the OP picture, it looks artificial to me, however I suppose it's possible it's a form of natural cloud... I just don't know for sure.

Also, I've seen plenty of pictures of "chemtrails" before and I've seen a number of documentaries on the subject and have done a decent amount of my own research, I also study weather to a degree as part of my photography interests so it's not like I don't know anything about the subject. I try to listen to all the different sides and keep an open mind.

PS... I remember I was suppose to respond to you in a previous discussion about flat earth stuff and I never got back to it. I apologize.
