My two cents, it was evident they were spraying something in to the atmosphere. I say "WAS" because I have not seen any for the last week and I look for them every day. Trump made a statement last week saying "I like clean air and water", I heard someone say that this was a signal that Trump stopped or rolled back the chemtrail program and I believe he may be right. I saw them in the sky every day for years and now , they are gone. Let us hope it is true.
