We were driving home from some kind of school-play at my school when I was like 11, and suddenly a blue-white circle flashed up in the sky. Like a blue lightning bolt doing a circle in the sky high above us, both my brother and I saw it. My brother said it can't have been some electrical fault in the poles, it was too high. So he just said it was some firecracker or something.. But it was straight above us, about 20mt. To this day i don't really know what it was. It was so big aswell
