Incident: 19 September 2026, Santiago, Chile. SEFAA case 2288, reported the same day; resolved 28 September and released 8 October 2026. Identification: drone in restricted airspace.
The photographer was watching the military air parade with family and neighbours from a high rooftop. A small shape appeared in a photograph of a Chilean Air Force E-3 Sentry. Initial estimates described a large, fast disc close to the aircraft, but the investigation distinguished those impressions from what the image could establish.
The camera record
The six-page investigation examines a Nikon D5300 NEF file recorded at 13:29:50. The lens information and exposure settings provided a more reliable account of the photography than a rounded recollection of the focal length. A shutter speed of 1/1000 second froze a brief view, not a measured trajectory.
The original claim included estimates of a ten-to-twelve-metre object travelling around 700 kilometres per hour. No independently measured range accompanied those figures. Apparent proximity in a two-dimensional photograph cannot by itself place a small foreground object beside the aircraft or establish its physical size.
Image assessment and a separate inquiry
SEFAA examined enhanced views and the shape’s edges and brightness. It assessed the object as much smaller than the initial comparison with the Sentry suggested and consistent with a drone. The report then connected this with an operational-safety investigation by the aviation authority, which identified an unauthorised drone associated with social-media recording.
That second source chain is an important part of the published conclusion. This entry attributes it to the authority’s report; UKPX has not inspected a recovered aircraft, an operator’s account or a separate complete enforcement file. The presence of an E-3 radar aircraft in the photograph also does not mean its radar detected or classified the photographed point.
A safety finding with a date
Unlike some other resolved reports in the same release, this file explicitly records a concern about a drone in restricted airspace during an aviation event. Its resolved classification therefore does not mean the occurrence was operationally harmless.
The report describes the matter as it stood on 28 September. It supplies no basis here for naming an operator, alleging an additional offence or asserting a later prosecution outcome. The 8 October publication is the source release date, while the incident remains tied to the September parade. A broad city pin preserves that geographical context without identifying the private rooftop or inventing the drone’s exact track.
