Six cylinders dark, not lit up. Flying in V shape formation .

This took place around 11 PM. The sky was clear with stars. We were sitting in our hot tub, looking up into the sky. Was perfectly sober. Just relaxing, 6 very large cylinder like objects, dark in color compared to the sky that was clear that night. They moved very quickly, but silently with no lights 6 information in a V-shaped. It was very silent, but very fast.. We live about 2 miles from Lake Michigan. The UFO was heading west from the size and the distance. I would say it’s banded around 100 feet across or span and about 30 to 40 feet thickness from front to back. And the speed that it was going comparable to the Jets that we see flyover at night from O’Hare airport or coming from that direction I had to be going way faster than any of our planes that we have in the sky again it was silent, very fast cylinder, six cylinder separate, or perhaps were joined in someway, but in a \/,shape
