While returning from the beach on vandenberg afb i rounded a corner and saw a large object hovering. i pulled off the road to catch a video and it slowly started moving! it was slightly behind a large hill , small mountain headed directly towards the tracking stations responsible for tracking all objects in orbit! i could not see any markings, tail fins or cockpit as you would expect to see from a blimp, however i was at a considerable distance but this was over an air force base and isn’t typical in this area!
