Last night around 7:30 PM I noticed an odd plane of some sort through my skylight windows of my family room. It cought my eye enough to look at it. It had rapidly blinking white lights that appeared to fly in a zigzag motion for a short period of time before darting off to the right, that is when I went outside with my husband to look at it. We noticed it was oval to disc shaped, flying fairly low, with all white pulsating lights almost giving it a spinning appearance. The lights seemed to be alternating on and off. It was silent.It moved quickly and was out of view within minutes.
