Guo was detained at the airport on King George Island. On June 29, he was charged with handing false information to ground control and landing without authorization, both breaches of the Chilean Aeronautical Code. The code calls for short-term imprisonment or a fine for anyone who lands on the country's territory without authorization.

The Chilean government dropped charges against Ethan Guo on Monday as part of an agreement that he donate $30,000 to a children’s cancer foundation.

Guo's attorney said the pilot received "explicit, direct permission" to land at a Chilean base. But upon landing, Guo was arrested and charged with providing false flight information, according to Chilean officials, who said he did not have a permit and "violated international regulations regarding the Antarctica continent."
