Four bright lights moving in formation south of Glenpool.Driving south on Hwy 75 towards Glenpool at night. It was very clear. The moon was out and stars were beginning to shine. Saw fireworks to my left and right. In the middle high above the fireworks 4 light objects appeared. They looked like stars. They appeared and the formation reminded me of the Big Dipper Constellation. I thought, that's not the Big Dipper, it should be in the North.As I watched, the objects started moving. The 2 in the center moved closer to each other towards a vertical position. The top one started moving towards the 2 lining up vertically. The bottom one was also moving in the same direction as it seemed they were going to line up eventually. The top object reached first, once it did, it then faded and was then gone. Then the bottom object got very close to lining up...it then faded and was gone. Finally, the middle two started moving towards each other vertically from the horizon. Once they got closer, they faded and were gone.I have never seen anything like this before.((NUFORC Note: Source of the report elects to remain anonymous; provides no contact information.
