2005-06-20 - Potomac Falls, VA - Triangle

I saw 3 lights at high altitude. At first I thought it was 3 separate objects but all 3 lights moved at the same speed (very slowly) directly over my head. It came out of the northwest moving toward to southeast, toward the moon. I could not see anything within the lights, but the light in front was slightly brighter than the two trailing lights. The lights formed a large triangle and almost came to a complete stop over my house. I couldn't believe it! It moved toward the moon and just disappeared. I also saw 6 other lights at the same altitude moving in different direction just prior to and after the triangle passed. None of the lights made any sounds and all moved very slowly. One very bright light stopped directly over my head and then moved toward the north very slowly and disappeared. This was about a minute before the triangle approached from the northwest. I don't know what they were, but I saw them. I've seen similar lights in the past, but never a triangle or lights that stopped. It was very cool! I don't believe in UFO's, so they were probably military aircraft. There were no flashing lights, so I wonder. All of the lights were white.
