I was driving from Thomaston towards Cushing Maine, when I spotted four or more chemical trails in the sky. The sky was crystal clear blue with unlimited viewing. The chem trails were unusual because of not only the amounts but the designs they left. There was an X design, as well as two lines parallel with dots in the middle. There was one that appeared to show the plane was banking left which appeared to be headed for Boston, while another was close and beside it. There was a third chem trail that showed a plane that was coming up fast as if to attempt to intercept the other two. These chem trails were strange not only in design but because the closest airport is Bangor, and there never been the amount of passenger planes taking off at the same time. The next day at work, I was discussing what I had seen, and a co-worker reported she saw the same and had taken some pictures. While we were looking at one of the pictures, when I noticed a black disc high above the chem trails hovering. I pointed it out to her, and she said she did not see that while taking the pictures. We checked other pictures she had taken with her camera and there were no other black spots. In summary, I now believe those were military planes that were chasing that flying disc. I have the pictures and will release them only to you. I will swear on oath that the pictures I have are not photo shopped or tampered with. I will mail them at your request. I do not have the camera they were taken with, and I don't want to have my co-worker involved in this matter.
