Driving south on wesley chapel blvd. immediately noticed something strange in the sky. it was moving way too fast to be a cloud. looked carefully at it and it was around 200 feet or so from the ground and about 1000 feet away from me. it was probably around 100 feet in length or so. no idea on width. gun metal gray / carbon fiber color. blended in with the storm clouds coming towards us but it was moving west instead of north. smoothly coasted through the air, fast as a small cessna. no lights. didn’t hear anything as i had my windows up. no electrical interference. only had 3-5 seconds to see it before it went over the trees.
