Ethan Guo, 19, had been documenting his attempt to fly solo to all seven continents on social media. He is no longer in custody but has no easy way to leave an island off Antarctica’s coast.

A teen from Massachusetts is currently being detained by authorities in Antarctica. Ethan Guo is accused of violating numerous laws while trying to fly to all seven continents. According to his lawyer, Gwo experienced in-flight complications and was forced to land in a region of Antarctica that has been claimed by Chile.

A 19-year-old pilot from the United States has been detained on an Antarctic island and charged by Chilean authorities, who say his flight to the frozen continent was unauthorized.
