A point of light moving in a very unconventional flight path.

I was watching the night sky on the roof of my parents garage as I usually did in the summer. I remember watching what I thought was a satellite, a pinpoint of light crossing the sky at a steady velocity, as I watched the light, traveling from north to south, it stopped for a moment then accelerated very quickly forming a "Z" in it's flight path and continued to the south at the same fast pace. A report filed by someone on 8/1/91 in Toledo OH desribes very much what I saw and at the approximately the same time of night and calendar date.
