Yea, I don't really know. It is pretty interesting to me that some of these "chemtrails" spread out so drastically though. I have watched them do it. I don't know if that is really normal but I feel like even contrails with the right conditions don't hang there for hours and hours spreading out until they are a thick haze. I live near DC so theres a lot of air traffic around here so I see a lot of planes. They don't all do that. I could just be straight up wrong though. I don't really know the physics/chemistry behind it.
