A 20-year-old American pilot and social-media influencer detained by Chilean authorities in Antarctica has been released and returned to Punta Arenas more than two months after an alleged unauthorized landing.
Ethan Guo, of Tennessee, who was attempting to become the first pilot to fly solo to all seven continents while raising money for cancer research, was detained in June after Chilean officials said he landed a Cessna 182Q on the continent without permission and presented "false flight plan data." Guo arrived back in Punta Arenas on Saturday aboard a Chilean navy ship and spoke to reporters upon disembarkation.
Guo told reporters his detention had been "mundane" with "limited freedoms" and praised the hospitality of Chilean personnel, saying they had taught him Spanish and "treated me like family." He was wearing a Chilean national soccer team jersey when he met the press.
Chilean authorities have said Guo presented flight information that did not match the operation he conducted. Under Chilean practice and the Antarctic Treaty System, flights to and landings within areas of Antarctica claimed or administered by Chile require authorization and coordination with Chilean authorities to ensure safety and environmental protections. The southernmost continent is governed by a combination of international agreements and national procedures for activities carried out from claimant countries, and enforcement of those procedures is carried out by the respective national authorities.
Guo had publicized his plans online as part of a campaign to raise $1 million for cancer research and to log flights to all seven continents. He was flying a single-engine Cessna 182Q at the time of the incident, according to Chilean statements cited by media. Details about any potential charges, fines or administrative measures have not been disclosed by Chilean authorities as of his return.
The timing and route of Guo's Antarctic landing, and the specific discrepancies Chile cited in his flight plan, were not detailed in statements released by authorities. Officials in Punta Arenas, a southern Chilean port city that serves as a common gateway for Antarctic missions, frequently coordinate scientific and logistical flights to research stations and managed landing areas such as those on King George Island.
Guo's release follows more than two months in Chilean custody. He did not provide further comment about possible legal proceedings or whether he would resume his planned flights. Chilean agencies have not issued a public timeline for any administrative or judicial follow-up.
The case highlights the regulatory environment surrounding civilian operations in Antarctica, where countries with logistical ties to the continent require coordination to protect the fragile environment and ensure safety. Guo's effort had drawn attention on social media because of his age and fundraising goal; authorities have stated that standard permitting and reporting obligations exist for flights that enter Antarctic airspace or land on ice or islands within sectors managed by claimant states.
As Guo departed the naval vessel, he reiterated gratitude toward the Chilean people and declined to elaborate on the circumstances of his detention. Chilean officials have not released a comprehensive public account of the investigative steps taken while he was detained or whether penalties will be imposed.
