On the morning of April 11, 1980, around 7:15, some 1,800 personnel assembled in formation in the yard of La Joya Air Base, in the Arequipa desert, observed a luminous spherical object hovering near the perimeter, a few kilometers away and at low altitude. Suspecting a foreign surveillance balloon over sensitive military facilities, the command ordered an interception. Lieutenant Óscar Santa María Huertas, about 23, took off in a Sukhoi Su-22 armed with 140 rounds of 30 mm cannon.

By his account, on his first pass he fired a burst of 64 rounds that formed 'a wall of fire' over the object; none seemed to damage it —the object absorbed the impact or dodged it with no visible effect. On the next three approaches, each time Santa María locked onto the target and was about to fire, the object climbed or moved away at high speed and stopped again out of range, in a pattern the pilot read as deliberate evasion. He came, by his testimony, within about 90 meters of the object, close enough to describe it in detail. The pursuit, at varying altitudes and toward high levels, lasted about 22 minutes. Out of useful ammunition and low on fuel, the pilot returned to base. The object —which he described as about 10 meters across, with a shiny cream-colored upper dome, like a light bulb cut in half, and a wide silver circular base— remained stationary in the sky for nearly two more hours, in view of hundreds of personnel.

The case stands as one of South America's best-attested military aeronautical files: a named, living protagonist, hundreds of witnesses at a military base, and behavior (active evasion of a fighter, resistance to cannon fire, prolonged stationarity) hard to fit a balloon or a natural phenomenon. Its limit is the absence of surviving instrumental record: no gun-camera film or published radar tracks are preserved, and the episode was not officially reported by the authorities of the time, which fed both its reputation as a 'perfect' case and the doubts of skeptics. Santa María testified publicly for decades —including before international forums and in the U.S.— and his account remained consistent until his death.

Es el caso peruano más célebre y uno de los pocos del mundo con un piloto militar disparando munición real contra un objeto no identificado — Óscar Santa María Huertas es, hasta donde está documentado, el único piloto que lo ha hecho. Su valor es testimonial e institucional: un oficial nombrado, una base militar como escenario, cientos de testigos y un comportamiento del objeto que tensiona simultáneamente la hipótesis del globo (no evade ni resiste cañón) y la del fenómeno natural (no maniobra contra un caza). Tier A y no S por la limitación dura: el episodio descansa sobre testimonio —muy consistente y sostenido cuarenta años— pero sin película de cámara de disparo ni registro de radar publicado que lo fije objetivamente. Encaja en la bifurcación que el corpus considera central: la sospecha inicial fue tecnología de vigilancia de otro Estado; lo que el piloto reporta empuja hacia algo que ningún globo de 1980 podía hacer.

Conviene, no obstante, sopesar las dos lecturas con honestidad. La fortaleza del caso es la confluencia entre un acto verificable y excepcional —un caza disparando munición real, registrado en el consumo de proyectiles— y la masa de testigos en formación. La debilidad es que casi todo el contenido anómalo (la absorción del fuego, la evasión inteligente, las dimensiones exactas) proviene de un solo narrador, sin imagen ni radar que lo respalde, y un relato repetido durante cuarenta años puede consolidarse y pulirse con el tiempo. El propio silencio oficial de la FAP, que algunos leen como encubrimiento, también es compatible con un episodio rutinario —fuego contra un blanco no identificado que resultó intrascendente— que nunca ameritó un informe público. El caso vive, por tanto, en la frontera entre un evento militar genuinamente extraordinario y un testimonio único e inverificable: por eso pesa, pero no decide.

It is Peru's most famous case and one of the few in the world with a military pilot firing live ammunition at an unidentified object — Óscar Santa María Huertas is, as far as documented, the only pilot to have done so. Its value is testimonial and institutional: a named officer, a military base as the setting, hundreds of witnesses, and object behavior that simultaneously strains the balloon hypothesis (it neither evades nor withstands cannon fire) and the natural-phenomenon one (it does not maneuver against a fighter). Tier A and not S because of the hard limitation: the episode rests on testimony —very consistent and sustained for forty years— but with no gun-camera film or published radar record to fix it objectively. It fits the fork the corpus treats as central: the initial suspicion was another state's surveillance technology; what the pilot reports pushes toward something no 1980 balloon could do.

It is worth weighing the two readings honestly, however. The case's strength is the convergence of a verifiable, exceptional act —a fighter firing live ammunition, recorded in the rounds expended— with the mass of witnesses in formation. Its weakness is that almost all the anomalous content (the absorbed fire, the intelligent evasion, the exact dimensions) comes from a single narrator, with no image or radar to back it, and an account repeated for forty years can consolidate and polish itself over time. The Peruvian Air Force's own official silence, which some read as cover-up, is also compatible with a routine episode —fire against an unidentified target that proved inconsequential— that never warranted a public report. The case therefore lives on the border between a genuinely extraordinary military event and a single, unverifiable testimony: it weighs, but it does not decide.
