Diamond shaped, mid day I videotaped it.I am a Police Officer and was patrolling on 03/17/2002 at 11:32am in Westchester NY.I saw something in the sky and videotaped it with the ‘In Car Video system that we just had installed in our patrol cars. I used the magnification of 128 on the camera to see what it was. When I realized it wasn’t anything I had seen before, I started taping it. The object was diamond/top shaped, and I followed it, moving my patrol vehicle several times to get a better picture. The actual video lasts 3:32. At one point a commercial plane flies past in the back ground. I have had the video transferred to DVD and have taken pictures of the images from my screen so I can send them out as attached files.
