On the morning of February 4, 1977, during recess at Broad Haven Primary School, a coastal village in Pembrokeshire county in southwest Wales, a group of pupils —about fourteen children, roughly nine to eleven years old— said they saw something strange in a field next to the playground, behind some bushes and at the edge of a sloping plot. They described it as a silver object, elongated or elliptical in shape —several compared it to a cigar or a saucer—, perhaps twelve meters long, settled or half-hidden in the vegetation. Some children added that they had seen, near the object, a humanoid figure dressed in a silver suit. The children ran to tell; at first the adults took it as a prank, but the insistence and the agreement among accounts led the school's headmaster to make a methodologically shrewd decision: he separated the pupils and asked them, individually and without communicating with one another, to write down what they had seen and draw it.

The result is what gave the case weight. The drawings, made separately, showed a concordant basic shape: a silver object with a bump or dome and, in several, an entrance or hatch. The consistency among independent accounts by children who had had no time to coordinate a story is the feature that has made the episode hard to dismiss as a mere joke. Broad Haven was, moreover, not an isolated event: it opened —or became the emblematic case of— a wave of sightings in the area throughout 1977, known as the 'Dyfed Triangle' or the 'Welsh Triangle', with reports from adults and children, including Ripperston farm and the figure of the 'silver man' said to have appeared near homes and hotels in the district.

The episode reached the British national press and the Ministry of Defence (MoD), which at the time kept a record of reports of unidentified objects. The MoD looked into it but never issued an explanation, and the case closed without conclusion; decades later, part of the MoD's files on the Welsh wave were declassified and transferred to the National Archives, documenting the official interest though not providing a resolution. The prosaic explanations are the usual ones for a mass school sighting: the misidentification of something ordinary in the field (a vehicle, a water tank, reflections), a prank that amplified, and above all social contagion —one child points, others 'see', and collective expectation shapes the accounts and even the later drawings. None was proven, but none requires anything extraordinary. The case stood as a memorable multiple sighting with no physical evidence: strong in witness numbers, weak in everything else.

It matters as the paradigmatic case of a mass school sighting, a category that recurs in the corpus (from Broad Haven in Wales to the Ariel school in Zimbabwe) and that poses a fascinating methodological problem: how much is agreement among many witnesses worth when they are all children sharing the same environment and the same expectation? The headmaster's decision to separate them and have them draw on their own is, in fact, a small improvised field experiment, and the concordance of the drawings is what lifts the case above anecdote. That is why it is Tier B and not lower: there is multiplicity of witnesses and an honest attempt to isolate their accounts.

But its real value for the corpus is as a reminder of the limits of that kind of evidence. Children are sincere observers but highly susceptible to social contagion: one only has to point for collective expectation to shape what the others 'see' and, afterward, what they draw. The concordance of the drawings can reflect a real object just as much as a shared image that crystallized in the group within minutes. There was no physical evidence, ground mark, photograph or instrumental record; the MoD looked into it and explained nothing, which in the case's mythology reads as mystery but strictly only means that a sighting with no material proof is not resolvable. The prosaic explanations —misidentification of something mundane plus social contagion— cover the facts effortlessly. For a catalogue that distinguishes the strength of the evidence from the nature of the object, Broad Haven is an honest Tier B: multiple witnesses and a genuine cultural episode (the Dyfed Triangle wave), about an object that in all probability was mundane and that no material proof managed to pin down.
