I haven't but my mum said in the 70s she was driving through Wales with her family and her and my aunt could both see a bbig bright light in the sky. It appeared to follow them and stay above the car, almost blinding light. They were shouting and pointing but their parents couldn't see a thing and told them to stop being silly.
They were both under 10 and still remember it vividly. She says it was a round bright light that moved smoothly and silently.
And my mum is not woo at all!
