In 1979, some friends and I were messing around with a video camera in a slum area of town that had largely burned down and never been rebuilt. The video camera was old, with a heavy, over the shouder separate deck, obsolete even then. We saw some stuff flying around the buildings. At first we thought they were kites or maybe some radio controlled toy planes. We never did figure out what they were, but we got some of the stuff on video. It appeared as if there were two things, one smaller than the other. They moved pretty fast, so we guessed they were light, like balloons.
