corkscrew chemtrail in air from unknown object

I have started to notice right around sunset lots of jet activity southwest of my residence.  I have tracked these movements accross the sky and they make no noise, they are incredibly fast and they rise up into the sky and disappear.  They are all coming from the same area, sometimes I will see 3 or 4 lined up in a row on the same path.  I thought they were jets at first, but I realized that we don't fly our planes that way, nor do they line up one after another, I have gotten 2 onto a picture at a time. They leave a wavy chemtrail.  I have 2 pictures that clearly show a chemtrail that looks like a corkscrew, as if the craft was spinning in circles as well as moving forward, and in one picture you can clearly see a hard turn in the chemtrail, our jets cannot do that.  I will send the pictures, you decide?
