Travelling horizontally, appro' 1 mile away, a green glowing fireball travelled with no sound.

During a camping week whilst in the boy scouts, the entire camp was around a camp fire singing songs. A car was heard travelling at high speed through country lanes, the only car heard that night. We all expected a police car chase but no other vehicle emerged from the country side. Within seconds we all saw a glowing green fireball travelling at what seemed a slow pace. We watched it for approx' three mins' during which it made no sound. It was guessed that it was about a mile away from us. The object travelled horizontally (east to west I think). The next day we all checked the local news papers for any reports, nothing was reported.
