Chile
Chile's Dirección General de Aeronáutica Civil (DGAC) established the Comité de Estudios de Fenómenos Aéreos Anómalos (CEFAA) in 1997 under the authority of its airspace-safety mandate. Renamed SEFAA (Sección) in 2014, the unit is one of Latin America's three continuously-operating national UAP programmes. Its monthly dispatches are public, investigators are uniformed DGAC staff plus civilian academics, and the catalogue is now ~280 cases deep.
Mission (verbatim, DGAC charter)
"El Comité de Estudios de Fenómenos Aéreos Anómalos tiene por objetivo el estudio sistemático de los reportes de observaciones de fenómenos aéreos anómalos en el espacio aéreo jurisdiccional chileno, con el fin de contribuir a la seguridad operacional aérea y al avance del conocimiento científico."
Why DGAC and not the Air Force?
The Chilean approach is intentionally civilian: CEFAA sits inside the civil aviation authority, not the FACH air force. This avoids the witness-suppression dynamic familiar in U.S./UK programmes and gives commercial pilots and ATC controllers a non-military reporting channel.
Roster
Investigative roster includes: a DGAC airspace officer (chair), a FACH liaison, an astronomer from the Cerro Tololo / Cerro Pachón observatory community, a meteorologist from the Dirección Meteorológica de Chile, and ad-hoc civilian academics.
Notable cases in the SEFAA catalogue
El Bosque 2010 — air-show video over Santiago, multiple amateur recordings, no aircraft tracked, no birds consistent with size. Investigated for 24 months; case "sin explicación".
Collahuasi 2013 — mining camp daylight observation, three witnesses, photo sequence. SEFAA finding: "objeto no convencional, sin explicación natural conocida".
Bahía de Quintero 2014 — coastal radar return corroborated by civilian video.
