I would'nt have believed it, I can only try and explain what we saw.I am not a freak, but if I hadn't of seen this last night I would think that it was a freak that wrote this. My husband (a well educated person) and I (an accountant) were traveling on highway 27 between Harrison and Mount Pleasant Michigan. We just left his brothers house near Crystal Lake going home to Livonia. We were discussing a quiz from my accounting class about ethics. The radio was off, and all I had on was my little flashlight (one of those small ones that help you find your lock on your door at night). I was reading an article to him from the New York Times, when we both looked out my window (looking West), and noticed two strobe lights on what looked like a long wing about four bus lengths apart from each other flashing three times each but at different times with no hesitation between the flashes from one side to the next. My husband said he noticed the lights reflecting on the car and I noticed the flashes from my peripheral vision. The first thing I thought of was the stealth, except it was longer and not what I would imagine the stealth to look like (granted I have never seen a stealth). The object was silent, but our windows were up, but we didn't hear anything! It was about 150feet high, no higher then 200feet up. It went right over our car from a bit south but more West to East South, and it was going around (best guess) 120-150 miles an hour. My husband asked as it went over to watch it, which I did, and noticed that its left strobe light turned off, it made a decent and disappeared for about 15sec maybe 20. I told my husband that it appeared to have landed in a thicket of trees but I couldn't be sure. When it suddenly showed up again and flying very fast from where I last saw it going now straight south but then we noticed it had red and blue lights flashing along with the outer white lights and again in a strobe light manner, they were in perfect sequence with each other. The craft went at least three miles in about 2 1/2 to 3 minutes tops. It appeared to land again, when we saw i! t cross the highway going south west again, it was closer then and we couldn’t explain that (about 1 mile if that away from our car at that point) as we got closer its lights went back to just the white strobe lights on the out side of the wings again, and at this time it was crossing east again in front of us still around a mile ahead of us away. It turned so fast North that it was next to our car again, (drive's side window) we watched it as it was now behind us around a 1/2 mile back again when we turned off the freeway (m20, Mount Pleasant exit) and stopped our car at the side of the exit ramp, we jumped out of the car and looked up. This thing should have flown over us, there is no doubt in my mind, when it turned from South to West again, it did it in a quick (and I mean quick) U turn and only two BRIGHT lights like car lights steady not blinking now, were coming over a trailer park that was right next to where we were parked now. It had to have been flying around 70 miles per hour (I would estimate) and it should have flown over us, I was standing on the car outside my door (you know that section of the car where the door meets next to your seat?) so I could see it as it went over better and closer. It never went over us, and I SWEAR it should have. My husband and I just looked at each other and asked, "Where did it go!" But we never saw it after that, we stopped at this gas station just about 1 block west from our exit ramp and I got out of the car and looked up while he pumped gas. I must have looked like a freak, but honestly nothing like that has ever happened to either one of us before. I never believed the stories of UFO's before, my husband has never dismissed the possibility of them, but now I don’t know what to believe. NOTHING COULD FLY OR TURN THAT FAST!
