Multiple lights, moving in erratic behavior, then flying south in uniform.

I saw some bright light that I thought was a shooting star from the west. I noticed it curved, much like a boomerang, only to vanish into thin air. This "bright light" would repeat this multiple times. After a few minutes, there were two bright lights that followed each other in a dancing fashion. These bright lights moved extremely quick, considering they were at about the height of an airplane. They made very quick, and sharp movements in the blink of an eye, only to disappear. After about 20 minutes, 7 bright lights left in uniform fashion (like the air force) heading south. The weather was foggy during the encounter, but quickly cleared up after the group of lights were seen leaving.
