Up to 4 UFO outside earths atmosphere

My copilot and I started seeing the objects while at 39,000 feet around Omaha, Nebraska. We were flying east to Detroit, MI from Las Vegas, Nevada. We seen as many as 4 objects at a time, traveling in multiple directions outside the earths atmosphere. They kept to an area just in front of the bowl of Ursa Major. It was almost as if they were playing with each other like a pod of dolphins. The objects looked like stars but moving at high speeds and changing directions. At times they would get brighter than any of the stars in the sky. They appeared to be way outside the atmosphere of earth. Total duration of the sighting was at least 2 hours. The magnetic bearing of the objects stayed at about a 035. Hence the reason along with other factors I believe the objects to be way outside earths atmosphere. This is my second time seeing these objects while I was flying through this same area.
