We were enjoying the evening sunset, as it glistened off the USX towers downtown Pittsburgh, in a north easterly direction. When we all for some unknown reason looked to our right and witnessed a star dancing in the sky. It appeared to just dance, back and forth up and down, then it came closer. Suddenly, it took off in a westerly direction, as we chased it. Two years later I would witness another event similar in nature in Georgia. While on bivevac training and standing guard with a Private Rodriguez, I saw a star dancing in the sky, similar to the one I seen, as stated previously. I related this story to Pvt. Rodriquez and wouldn't you know it. The star did the exact same thing. With one exception, I ran to report it to my drill sargent, he thought i was a lunatic. When I stepped out of his tent some 10 meters away, a stealthy black object appeared above me. See my second reporting to finish this story.
