I was doing some wood working in my shop in the backyard. I could her a loud humming sound. I was not using and machines that night I was carving. When I first saw it I ran back and retrieved my phone. When I first seen it I new it was not normal. The object was shaped like something shaped as a boomerang / triangle. It was hovered over a group of houses a cross the street. It was making a loud humming sound that started to change to a vacuum sound. It was moving very slowly then changed direction to the west. I was trying to get a good picture of it. As I was taking a picture it made weird noises like a swishing sound then it was gone. I was pretty shocked over the whole thing. I could not get it out of my mind for a few weeks.
