At about 9:40 Central time on 3/8/13, I was watching tv. I noticed a very bright white light coming towards my house. I live on top of mountain and can see for several miles over the Cahaba Management area. I grab my phone and go out on the deck and watch it approach. I cant hear anything until it is right on top of me. It was maybe 100/125 feet above me and it was huge, triangular, dark in color,with maybe 20 lights on the underside. It looked to be maybe 150 feet wide at the rear. It looked to moving maybe 50 mph max. As it crossed above me it got loud. The sound was like jet engines spooling down. It crossed over my towards Bessemer airport. I ran through the house and out the front door to video some more but I could no longer see it. This thing looked like a Stealth fighter but 5 times bigger. Way too big to land at Bessemer. It freaked me out completely. Since then, there have Chinooks behind my house constantly.
