The 1977 Dyfed Triangle Incursions: Declassified MoD Files and the Broad Haven School Incident

The Broad Haven School Account

On February 4, 1977, fourteen pupils at Broad Haven Primary School in Pembrokeshire, Wales, reported seeing a silver, cigar-shaped craft land in a field adjacent to their playground. The children, who were interviewed separately by their headmaster, Ralph Llewellyn, provided strikingly consistent drawings and descriptions of the craft. They also described seeing a 'tall figure in a silver suit' emerge from the object. This event triggered what would become known as the 'Dyfed Triangle' wave of sightings.

Military Presence and Investigation

Following the school sighting, the Pembrokeshire region witnessed a surge in UAP reports, including an incident at the Coombs farmhouse where the owner, Rosa Granville, described a saucer-shaped object and two humanoid figures in silver suits. The intensity of the sightings prompted an internal investigation by the Ministry of Defence (MoD). Declassified files released under the Freedom of Information Act reveal that the MoD's 'UFO desk' was contacted by local police, who were overwhelmed by the number of credible witnesses.

Declassified MoD Documentation

The files, now housed in the UK National Archives, show that MoD officials were skeptical but took the security implications seriously. A memo from the Provost & Security Service (the RAF’s internal police force) noted that the descriptions provided by the children were unusually detailed for a mass hallucination. One particular document suggests that the MoD discretely investigated whether the sightings were related to secret military exercises at nearby RAF Brawdy, though no such exercises were ever officially confirmed to have taken place at the time of the encounters.

Historical Significance

The Dyfed Triangle remains one of the UK’s most significant UAP events due to the sheer volume of civilian and police testimony. Unlike many cases that rely on a single witness, the Broad Haven incident involved a large group of children whose testimony remained consistent decades later. The MoD’s eventual conclusion that the sightings 'offered no threat to the defense of the UK' served as a standard bureaucratic closing, yet the internal documents reflect a higher level of official concern than was publicly admitted.
