Ethan Guo, a 19-year-old aviator from Memphis, was detained and charged with submitting a false flight plan before traversing towards the South Pole on June 28, the Magallanes and Chilean Antarctic Prosecutor’s Office. Guo is aiming to raise $1 million for cancer research with his high-flying campaign across the globe.

A teenage pilot, who is attempting to fly across seven continents solo, hit a patch of rough air this weekend when Chilean authorities detained him for changing his flight plan without their permission and landing in Antarctica.

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.
