I had been riding my motorcycle and came home late at night, and I knew being a star gazer to always look up late at night to hopefully see a shooting star. I got way more to see than I hoped for. I looked straight up facing the South and instantly caught six pinpoints of light traveling West to East almost straight up; a little South far outside our atmosphere. 1-white pinpoint light leading, 2-perfectly spaced very far behind & spread far apart from each other (given how very many miles up they were); then 3-very far behind and perfectly spaced very far apart to each other. I knew with my excellent vision & familiarity of what satellites look like passing by with moonlight reflecting on them; these were craft under intelligent control, traveling together in perfect synchronicity; way, way, way outside our atmosphere. I ran in the front door finding my mother & father in the unlit living room watching TV. I urged them "Hurry up, hurry up, I want you to see this". Going back outside to the driveway with them in tow & looking up; the lights were now visible for about 30 seconds heading straight East. I knew what I saw before getting my parents outside to see them. There is no question in my mind of what I saw. Silent, they were just passing by & I luckily saw them. I cannot give an exact date unfortunately in regard to matching others possibly seeing them. I had this motorcycle and rode it in Michigan from April 21, 1979 until I moved to Dallas TX in about April in 1982. That is the span of time when this occurred. In a warm weather month in the state of Michigan 20-miles North of Detroit. Either '79, '80, or '81.
