2 large, dark silent objects hovering over Boulder Colorado on the morning of Nov. 6th.

I live on Flagstaff Mountain in Boulder, CO and was driving into town around 9:30am. on Nov. 6th, 2021. We see a lot of hang gliders, parachutes, etc, so I didn't think too much about the objects when I first spotted them. We also have NCAR (National Center for Atmospheric Research) out here, so I've seen weather balloons before, as well. As I drove closer into town, down the mountain, I noticed they weren't descending, which was odd.
As I almost got down into town, 2 fighter jets flew by, that's when I decided to pull over and film. Again, I know we have a large Air Force base in Colorado Springs, so not super unusual to see some fighter jets, but quite interesting I saw them during this moment. The objects were silent and hovering together, also too large to be drones. I wish I had a way of demonstrating size, but they were in the distance and definitely too large for drones.
I watched for as long as I could, I had to get to an appointment, but I lost sight of them after driving into Lafayette, about 5 miles from Boulder. I drove up to another high spot and couldn't find them anywhere in the sky. Watched the news hoping someone else might have recorded or seen these objects, but I haven't found any info. Hope you guys could find an explanation.
Thanks for your time.
