A publicity drone carrying a 1.2-metre (4 ft) symbolic ballot box became lodged on the roof of the Chamber of Deputies building beside La Moneda in Santiago at about 09:20 on Monday, forcing a 30-minute pause to a parliamentary morning sitting. No injuries were reported; the drone operator and three municipal roof technicians retrieved the box and disassembled the unmanned aerial vehicle (UAV) on site, and a Ministry of the Interior inquiry into the incident was opened later in the day.
The demonstration, convened by the civic group Civic Voices to press for amendments to electoral transparency rules, drew roughly 200 people to Plaza de la Constitución. Organisers had planned a theatrical aerial drop of the oversized ballot box as a visual symbol. City officials said the hexacopter — capable of lifting 8 kg (18 lb) — lost telemetry while transitioning into a municipal drone corridor and made an unplanned landing on a low section of the deputies' roof.
Eyewitnesses said the scene was more comic than alarming. "It was theatre rather than terror — people clapped when it settled," said Luisa Millán, a Civic Voices organiser who had been standing near the temporary stage. Nearby, the Wunors Ensemble, a street theatre troupe that had been warming up with short sketches about justice, broke into applause and snapped selfies with the stranded box. "We expected a stunt, not a building job," Millán added.
Parliamentary staff confirmed the roof landing led the Speaker's office to delay the morning's agenda by half an hour while safety checks were completed. "Our first priority is always members and public safety," said André Matos-Queirós, a parliamentary aide who coordinated the emergency response on site. "The quick action by roof teams and civil defence meant we could resume business without any real harm done."
The Aeronautical Safety Office within the Interior Ministry said preliminary checks pointed to a brief handover error between the city's newly trialled municipal drone corridor management system and Santiago Airspace Control, which is responsible for low-altitude urban airspace. "We saw a short, high-latency data exchange during a controlled handover that likely confused the autopilot," said Linda Nemes, an Aeronautical Safety Office engineer. The drone's operator, start-up Skyrun Drones, accepted responsibility and said it would temporarily ground similar promotional flights while the technical cause was investigated.
The incident prompted an easygoing exchange across the political spectrum rather than recrimination. Green MP Sylvia Jönsson-Karlsson, who watched from the public gallery, said the episode was a useful reminder that civic spectacle and public safety can coexist. "It was inconvenient, but harmless — and it focused attention on the reforms being campaigned for," she said. Opposition deputies called only for a short audit of approved drone permissions; none sought to escalate the matter into a partisan fight.
Organisers said they would continue their campaign and planned a more modest, tethered ceremony later in the week after consulting with authorities. The Aeronautical Safety Office promised a written report within 30 days and said it would recommend new operational checks for publicity flights in the central corridor. Social media users had a field day: images of the ballot box on the roof were shared widely, and the retrieval operation — filmed on several phones — drew chuckles as municipal workers lowered the box to cheers.
By late afternoon the real ballot box the activists had intended to use was accepted at a municipal civic centre and the demonstration's petition was logged with the Electoral Transparency Commission. The Interior Ministry said it would not fine the organisers for the symbolism stunt but would issue a warning to unauthorised commercial drone operators pending the outcome of the inquiry.
