On February 4, 1977, a group of children at Broad Haven Primary School in Pembrokeshire said they saw a large silver cigar-shaped craft with a dome land in a field behind the school during their lunch break. Some said they saw a silver figure near it.
The headteacher, Ralph Llewellyn, did not believe them at first. On Monday, February 7, he separated fifteen of the children and asked each to draw what they had seen; the drawings were strikingly alike. The story made national news.
The sighting was the start of a wave of reports along that coast that year, later called the Welsh triangle or the Broad Haven triangle. Explanations offered have included a sewage tanker and a prank, but several of the former pupils have said as adults that they still remember it the same way.
