Big triangle shaped craft with two bright lights just above tree line. It vanished as I got passed.I was on my way to work driving along the Mountain Parkway when i saw something large in the sky ahead of me. I wouldn't have noticed it if it weren't for the lights on the front. It was just above the trees and sat motionless. From the distance I thought it was perhaps a plane or a helicopter but as I drew nearer I saw that it had a triangular shape and didn't wasn't making any sound. I pressed the gas harder and quickly hurried on down the road. I chanced a look back and was shocked to that it was gone. Where could something that big go that fast?
