Ethan Guo is a 19-year-old Asian American pilot and influencer pursuing a historic solo flight to all seven continents in a small aircraft to raise $1 million for cancer research at St. Jude Children's Research Hospital.[1][3][4] Inspired by his cousin's 2021 diagnosis with stage 4 blood cancer, Guo began the journey in September 2024 from Memphis, Tennessee, visiting hospitals on six continents—North America, South America, Europe, Asia, Africa, and Australia—to meet child cancer patients and promote awareness.[1][3][4] Guo developed his aviation passion at age 13, earning a private pilot license at 17 through homeschooling to prioritize training; he is now IFR-rated, capable of instrument-only flight.[1][4] He has logged over 700 flight hours, visiting all 48 contiguous U.S. states and crossing the Atlantic three times.[1][4] Funds come from social media content, collaborations, and donations via his website.[1][4] In chess, California's Candidate Master Ethan Guo excelled at the 2025 FIDE World Cadets & Youth Rapid & Blitz Championships in Rhodes, Greece (April 13-17), winning gold in Under-12 Open Blitz (10/11) and bronze in Under-12 Open Rapid (8.5/11), gaining over 100 FIDE rating points.[2] Currently, Guo faces a setback in Antarctica, where Chilean authorities grounded his plane, alleging he deviated from his approved path into a Chile-claimed sector without clearance and filed a false plan.[1][3] Stranded at a remote outpost with daily costs of $600, he risks prosecution unless he pays $30,000 to a children's cancer charity within 30 days, leaves Chile immediately, and stays out for three years.[3] His lawyer cites mechanical issues on an exploratory flight, disputed by prosecutors.[3] Compliance could allow departure by early October via military vessel or commercial flight.[3]
