I was 18 at the time,and a group of us meet up every evening below a tree in a park discussing various events.On this evening about 5 oclock we all saw this ball of fire about 3 lampposts high travelling on a dead straight
route silently it just kept going until it disappeared in the distance.
Funnily enough we all just shrugged it off unable to think what it could have been.It has bugged me for years.Sure would like a possible explanation.
