Saw what looked like a small jet going oddly fast across the sky on a clear day, when it changed into two white tictacs close together

I was walking north along Major Taylor Boulevard when I saw what looked like a very fast moving private jet (white sliver) It caught my eye and the more I looked, the odder it became. It wasn’t too far up in the sky, and at one point looked like two white balls/tic tacs flying in unison next to each other, and then again switched back to looking like a white sliver, the original shape which I thought looked like a private jet. I checked flight radar and there were no flights in the area at the time. Unfortunately, I only had the chance to take pictures and so there is no video. I also attached flight radar info to confirm it was not a private jet.
