On the night of 28 December 1988, residents of south-western Puerto Rico reported a huge triangular craft over the Sierra Bermeja, pursued by jets that witnesses say vanished beside it. This is the record of what was reported, not a verdict on what was over the hills.
On the night of 28 December 1988, at about a quarter to eight, residents across the south-west of Puerto Rico watched a large craft move low over the Sierra Bermeja near Cabo Rojo. The tellings describe a huge triangle showing a light that shifted from blue to yellow. Jets went up after it, and most versions of the story identify them as US Navy F-14s. What witnesses describe next is what made the case famous. As the jets closed in they appeared to vanish in mid-air beside the object. The craft is then said to have split into two parts in a soundless luminous explosion and departed, while three small red balls of light chased a third jet.
What is on the record
The case's fame rests on scale. Every telling puts the crowd at over a hundred witnesses, and that figure is the sources' claim. The archive itself resolves five claimants across seven videos on two channels, and only two of the five are individuals: Jorge Martín, the investigator who collected and promoted the case, and a witness named Carlos Manuel Mercado. The rest are group entries standing in for the unnamed hundred.
The vanished jets were never matched by any documented loss of aircraft, and the accounts disagree about official involvement. One has the FAA confirming that F-14s flew from an airfield in the Bahamas while the Americans denied it. Another traces the jets to Roosevelt Naval Station despite denials. No document of any class sits in the file, so every strand of this rests on retelling.
Why it sits where it does
Cabo Rojo grades L3, the archive's independent-testimony tier, on multiple claimants describing one connected event. The grade measures the breadth of the testimony, not the truth of the vanished-jets claim, which nothing in the file corroborates. What the record holds is that many people reported a large low object over the Sierra Bermeja that night, and that the story has been retold ever since. What it was, and what happened to the jets, is not resolved here.
