We were driving South on Route 385,from a relative's place,(there were 3 of us in the car), when we seen what we thought was a low flying plane. It was a Bright White Sphere, that had gold transitioning into the white, and then back to white again. There were no flashing beacons, and it was moving along pretty good in a south westerly direction, then it just stopped above the ridge, and hovered there. That's what caught our attention. We pulled over to the side of the road and you could hear a distant throb, like "whoom,whoom,whoom". Judging from it's position in the sky we figured it would have to be pretty large. Then we seen two aircraft coming towards the object, they had beacons, and one was coming from the East and one was coming from the West, we figured they must be chase planes, and then the object started moving South and zig zagged about 4 times before heading due South and up, it's size diminished and then it disappeared, one plane followed the light, and the other kept heading East, since it was still pretty well a full moon, we were able to see the vapor trail which meant that the chase planes would have been jets. The object left no vapor trail. we continued on home, hopefully we'll get to see this object again soon.
