Glowing UFOs caught over Westminster, Colorado

On August 18, 2016, an automobilist was driving on a road located in Westminster (Colorado). After seeing fighter planes, he took a couple of pictures. Later, he noticed several bright UFO in the sky. What is it?

Witness statement:

I was driving northwest on highway 36 going towards Boulder when I noticed a group of old fighter planes flying above me. I immediately opened my camera on my phone and took two quick pictures of them. Later on in the day, I looked at the picture and zoomed in to not only see the planes but 2 ufo's flying at a 45degree towards the planes with a trail behind them. That's when I seen 5 more ufo's hovering below the clouds watching on it seemed. I was super excited to see what I captured and couldn't wait to show my family. They think I'm dumb for always watching ancient aliens, and other shows but changed their tune once they seen my picture.
