track pattern of lights

My friend, my brother and myself seen a series of lights in the sky that could have easily been described as airplane lights except for their speed and the way they flew. I cant say that there were any colors in these lights that was out of the ordinary either. They were just white. The behavior of the lights is what caught our attention.
We were outside about 10:00 and noticed what can be discribed as a very small pin of light. Just like that of an airplane very high in the sky. One at a time we noticed these lights coming out of the northern sky over top of us to the south and than breifly stopping (for less than 5 seconds) and shooting at an extemely high rate of speed directly to the east. It was definately not a normal aircraft because the acceleration was almost instantanious not to mention the the perfect 90 degree angle they were making to the east. We witnessed this about seven times in row that night all following the same exact pattern over the same exact tract in the sky. None of us are astronomers or anything but common sense leads us to know that this was not a natural thing. You could tell these were controlled and determined objects. The timing and speed of the objects were all the same in a very disciplined pattern.
As this event occured, the 3 of us commented on what we thought it was. Nothing we came up with then or even to this date has satisfied me. It was not your classic UFO sighting with lots of excitement and awe. What we all seen that night was not explainable.
Date is approximate.  PD
