The fourth light came from the same area as the other three lights and was the same color. This fourth light had two smaller blue-green lights around it that were in constant motion. This group of lights traveled in a northward direction but on the west side of Long Lake. The lights were to the Southwest of our location and stopped and hovered for awhile. All of a sudden, there was a popping sound. Immediately, the larger orange-yellow light disappeared and two smaller orange-yellow lights fell to the ground. One blue-green light stayed in place while the other one raced to the north.
