TL;DR

Peruvian Air Force Lt. Oscar Santa Maria Huerta fired 64 rounds of 30mm cannon at close range with no effect, the object then climbed beyond his Sukhoi-22's 63,000-foot ceiling while appearing to anticipate his weapons lock on three separate attempts, and approximately 1,800 ground witnesses at La Joya AFB observed the entire 22-minute engagement - with both the Peruvian Air Force and a US DoD cable officially documenting it.

Confirmed

  • Lt. Huerta was scrambled from La Joya AFB on April 11, 1980 and fired 64 rounds of 30mm cannon at an unidentified object with no observable effect (Peruvian Air Force official documentation)
  • The object climbed beyond the Sukhoi-22's operational ceiling of approximately 63,000 feet during the pursuit (official incident record)
  • Approximately 1,800 military personnel and civilians at La Joya AFB witnessed the engagement simultaneously
  • A US Department of Defense cable registered the incident describing the object as of unknown origin; Huerta gave sworn testimony at the Citizen Hearing on Disclosure (May 2013)

Unresolved

  • ?Whether the Peruvian Air Force's internal incident documentation, not yet publicly released in full, contains additional sensor data or analysis
  • ?Whether the US DoD cable has been fully declassified and whether additional US intelligence community records on the event exist
  • ?The nature of the object's apparent response to Huerta's targeting lock - whether this represents genuine intelligent evasion or coincidental performance characteristics

Strongest mundane explanation

A high-altitude research balloon (Transosonde type) is the primary skeptical hypothesis - but it is ruled out on basic physics grounds because no balloon can hover stationary at 600 meters, accelerate to match a supersonic fighter at approximately 1,000 km/h, climb to 63,000 feet, or perform directional evasion in response to targeting lock; no conventional or experimental aircraft of 1980 matches the observed performance profile.

On April 11, 1980, Peruvian Air Force Lieutenant Oscar Santa Maria Huerta was scrambled in a Sukhoi-22 supersonic fighter to intercept an unidentified object violating restricted airspace above La Joya Air Force Base. He fired 64 rounds of 30mm cannon at the object from below - with no effect. The craft then climbed and accelerated, drawing Huerta into a 22-minute pursuit covering 84 kilometers before reaching altitudes exceeding the Sukhoi-22's operational ceiling of 63,000 feet. The object displayed no wings, no exhaust, no propulsion mechanism, and appeared to anticipate Huerta's weapons lock on three subsequent attempts. Approximately 1,800 military personnel and civilians on the ground witnessed the engagement. The U.S. Department of Defense registered the incident, and Huerta later testified under oath at the Citizen Hearing on Disclosure and documented the engagement in Leslie Kean's peer-reviewed book. It remains one of the most thoroughly credentialed military pilot UAP encounters on record.

Key Facts

  • Date: April 11, 1980, beginning at approximately 7:15 a.m. local time
