All silver perfect circle moving 30 times afaster than any plane in the sky.Mind you the ground is covered with alot of snow pack so I was surprised to see a large silver circle object traveling Northat at least 30 times that rate at which high altitude planes travel and away from the sun. ALl the planes up there criss crossing then I see this thing just bolting in a unimanagable rate of speed and going in a straight line. This could have been reflection of high noon sun on a passing satelite. Either way it had no wings and was way above the highest of planes in the blue sky. No trail what so ever. All silver perfect circle.
