Two witnesses were in the back yard about 1am and one noticed a set of lights flying erratically. When they both focused on it they describedthe pair of lights as; quick and erratic, touched and overlapped each other, dogfighting, moving together swinging and zigzagging up the sky, the back one followed the other one more or less, like two balloons tied together, moved really fast, faded slowly and disappeared directly overhead. They were watched moving from an east to west direction which is contrary to normal movement from that location. One witness (color blind),claims to be a long time sky watcher and has never seen anything like this in the sky. The other witness describes 2 pale blue or green lights.
