Flaming sphereical object hovering and disappearing as jets neared its postion like a cat and mouse game.Tonight once again a UFO was hovering and disappearing to the north of this rig. This time it was further away. But here's the good part, 2 jets were swarming this thing and right as they got kind of close it would disappear. Once the jets flew by were it was it would come up a little ways away from were it blacked out. These jets when it would light back up (UFO) they would turn in a bank and come back and just watching these jets was wild the way they were "chasing" the UFO. Those things can move fast. But once again the night time crew saw all of this also and with my co-worker & I and the crew that makes 7 witnesses. At what I would call the end of this sighting it looked like something fell right where it was located. It looked like a meteor but as it neared the ground in about a 45 degree drop it seemed like it righted itself and paralleled the ground then disappeared again.
