Neon green flying object seen over Gillette, WyomingAt first glance it seemed to be a shooting star, but it was larger than a star and was neon green and was flying horizontally. It has a large streak behind it, because it was moving at such a high rate of speed. My husband says it appeared to be the size of a football, but was at least 2,500 feet in the air. It went through the clouds and you could still see the glowing green and it's streak behind it, then appeared in the clear sky and 'took off.' My husband says it seemed to go at least 700-800 mph.
