A 20-year-old American pilot and social media influencer, Ethan Guo of Tennessee, was released from Chilean custody and returned to Punta Arenas on Saturday after more than two months detained in Antarctica, Chilean authorities and Guo said.
Chilean officials have said Guo was detained in June after landing a Cessna 182Q in Antarctica without authorization and presenting what authorities described as "false flight plan data." Guo had been attempting to become the first pilot to fly solo to all seven continents and said the trip was also intended to raise $1 million for cancer research.
Guo arrived back in Punta Arenas by Chilean navy ship and spoke to reporters while wearing a Chile national soccer team jersey. He described his detention as "mundane" and said his freedoms had been "limited." He also praised the Chilean people, saying, "They’ve been fantastic people. They’ve taken care of me. They've taught me Spanish, and they've treated me like family."
Chilean authorities have alleged that Guo landed the aircraft without the required permissions and provided inaccurate flight-plan information, assertions that led to his detention on the Antarctic continent. Details of any formal charges, fines or legal proceedings have not been made public by Chilean prosecutors in the initial accounts released by authorities.
Antarctica is governed by an international treaty system that designates the continent for peaceful and scientific purposes, and nations with Antarctic operations maintain regulation and supervision over activities on the territory they administer. Chile maintains a long-standing presence in the region and operates bases and logistical support from its southern port cities.
Guo had publicized the multi-continent flying attempt on social media, framing it as a personal endurance goal and a fundraising initiative for cancer causes. His flight to Antarctica and subsequent detention drew attention to the logistical and regulatory requirements for private aircraft operations in the region, as well as the risks of remote landings in harsh polar conditions.
Guo's immediate plans following his return were not disclosed in detail. Authorities and his representatives did not immediately provide further information on whether any penalties, traffic infractions or other legal measures would follow. The circumstances renewed discussion among Antarctic operators and regulators about oversight of private expeditions to the continent and the enforcement of permitting rules.
News outlets that first reported Guo's detention said he was held for more than two months before being released. Officials in Chile and representatives for Guo did not provide a public timeline for any ongoing investigations or administrative actions related to the alleged unauthorized landing.
