UFO Sighting in Albany, Wisconsin on March 2nd 2016 – Shape circled like a hawk but up and down then took direct path SE

I heard multiple loud jet noises which is unusual due to our rural location and nearest flight path. I'm former Air Force and thought one of the sounds was like a fighter not a commercial aircraft because it was so loud. Went out on the porch to look for craft making the noise. Saw a white object about 20 degrees above the sight-line of the barn which initially looked like a white bird circling like a hawk on a thermalcline but not just around but in an upwards and downwards circular pattern very slowly. I did not see any fighter planes. The object looked as if was a "v" shape or had rectangular wings. The object stopped circling and then appeared a solid wing-less shape. The object took a direct and very straight flight path at the same altitude S/SE without making a sound. The object when moving S/SE looked like a solid shape without wings. I was about to run in a grab my camera when it began its S/SE path and I wouldn't have had time - so I just observed it.
