Three lights moving in the sky.Two white,one red. The size of a small aircraft light. Form a triangle and then shoot off backwards.

I was sitting in a parking lot, with my children, waiting for my husband to get off work. I noticed a light in the night sky that was going north at a slow speed. At almost the same time, I noticed an exact light going south. With a small airfield a few miles away, I assumed that they were light aircrafts. They were approaching each other at the same level and I began to wonder if they weren't going to come close to hitting each other.  That's when I noticed a third light of the same size, only red, coming straight down from the sky, due center of the other two.  The three of them silently continued on their courses until they were [a thumbs width] from each other. They stopped for 4-5 seconds, forming a triangle, and then simultaneously shot off backwards in the directions they had come from and disappeared in seconds.  I was speechless until I heard my 8 year old son shout,"Wow!" from the backseat. "Did you see that?", I asked excitedly.
We both enjoyed the show, that's for sure.
