a strange flash seen in sky showing evidence of ufoTwo of my friends and I were walking around town when one of us described seeing a flash across the sky. We first believed it was lighting but with the absence of clouds, noise and it appearing in different colors we began getting concerned. It continued for another 20 min showing in different brightness levels and colors. We tried to show a parent but it wouldn’t show. It stopped for about five minutes and began once we tried to show another parent who witnessed it. We did some research and found similar sightings near the area over the years.
