3 craft flying pallalel, no sound,

I saw crafts in the sky they were very high up in the atmosphere, I saw one large craft bigger than the other 2. I lost sight of the craft above me. Searching to find it. I turned around and saw three crafts stacked flying west, they were also Lower in the sky they had no sound. With jets or airplanes I can hear motors and or rotors. But these had no sound at all. I ran back upstairs to grab my SO and took him on the balcony to see, and he saw them also. We watched them for about Two minutes before I we lost visibility. I also had to leave for work. I drove to work in the same direction following I-44 about 4 minutes later and I didn't see them at all. I hold a bachelor's degree of business and I have had astronomy. The 2nd witness is former military, and also has a bachelor's of environmental science degree.
