I think many of us have witnessed something inexplicable. Mine was in 1983. Worked late into the night with 5 colleagues. As we left the building, heading to our cars we saw a glaring light hovering over back security fence. It moved & I felt real fear. Beyond that fence only acres of scrubland. The light was blinding & we agreed to drive out together & formed a cue heading to motorway.
Next morning I could see nothing which would cause such intense light & heat. We all discussed it but didn’t tell bosses for fear of being laughed at. Still bothers me today.
