What was intended as a fundraising mission for cancer research has become a nightmare for American teen influencer Ethan Guo, who has been stuck since June in a remote location in Chilean territory in Antarctica.

Authorities say Guo landed his small plane illegally after providing false flight plan information to officials who opened an investigation.

Guo made headlines last year when the then-19-year-old began a trip in an attempt to become the youngest person to fly solo to all seven continents and, at the same time, collect donations for research into childhood cancer.

As part of his trip, the teen, who identifies as Asian American, planned to go to Antarctica, but according to the authorities, he lied to officials by providing authorities with false flight plan data. Prosecutors said he had been authorized to only fly over Punta Arenas, but that he kept going south, heading for Antarctica in his Cessna 182Q—a single-engine light aircraft known for its versatility.

Guo was charged on June 29 with handing false information to ground control and landing without authorization, but a judge dropped the charges as part of an agreement with his lawyers and Chile's prosecutors. It requires the teen to give a $30,000 donation to a children's cancer foundation within 30 days to avoid a trial. He must also leave the country as soon as conditions allow and is prohibited from reentering Chilean territory for three years.

After the judge's ruling, Guo told The Associated Press in a text message that he was relieved by the outcome.

For the past six weeks, since being charged, he has stayed at a military base. He was not forced to stay there, only to remain in Chilean territory, but because of the severe winter in that part of the Southern Hemisphere, there haven't been any available flights he could take. And he has been unable to fly his Cessna.
