My sister called five minutes ago and told me to go outside and look up to see a triangluar vechicle moving through the sky with red and white flashing lights. I have never seen anything like that before. I googled the discription and found nothing to suggest what it is and might be doing. We do live in an area with a large military presence as well: Cheatam Accex, Northrup Grummon, Naval Weapons Shipyard,, Navy Base in Norfolk, Langley/ Fort Eustus etc. So was it a spy plane; if not what was it?
