A 19-year-old American pilot, attempting to fly solo across all seven continents, has been detained after going off course and landing in Antarctica without permission.

Teenage aviator Ethan Guo was detained by Chilean authorities after he flew to an Antarctic base without authorization.

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.
