Ethan Guo, the 20-year-old American pilot on a quest to become the youngest person to fly solo to all seven continents to raise money for cancer research, has been allowed to leave Chile after being arrested and stranded there since June, when he made an emergency landing in Chilean Antarctica.
Chilean authorities allowed Guo to leave a military base on King George Island off Antarctica on Saturday.
Guo had been stranded on the island for more than two months after Chilean officials said he was arrested and charged with providing false flight information and landing there without a permit. In a case that has since been suspended, Chilean officials initially claimed Guo "violated international regulations regarding the Antarctica continent."
A Chilean court suspended Guo's case early last month and ordered him to donate $30,000 to a local charity in exchange for the charges being dropped, according to Guo. He is also barred from re-entering Chilean territory for three years, Chilean officials said.
In a statement to ABC News after being allowed to leave King George Island, Guo called his legal entanglement "deeply unfair" and said his legal team is now considering further action.
"As I have maintained from the start, I faced an in-air emergency and was granted approval by Chilean authorities to land on King George Island," Guo said in the statement. "I am pleased that the agreement with the prosecutor's office closes the matter with no charges filed and no penalties imposed. This resolution reflects the facts."
Guo, who departed King Island on a Chilean Navy ship, said that "as a gesture of goodwill," he is donating to Fundación Nuestros Hijos, a children's cancer charity in Chile.

"My phone and documents were taken and I was prevented from sharing them with my attorneys. During the initial proceedings, I was not allowed to present evidence, and the public defender assigned to me neither spoke English nor was supported by a translator."
Guo said he hopes to resume his plan to fly solo to all seven continents. Guo's attorney told ABC News that the Chilean government would not allow the adventurous pilot "to fly his airworthy plane off the base."
"We are coordinating with Chile's aviation authority, who have been supportive in arranging for another pilot to fly the aircraft to the mainland. Once that occurs, I look forward to resuming my global fight against cancer," Guo said.

He said he diverted to Antarctica and landed at the military base on King George Island with "explicit, direct permission" from Chilean authorities.
The pilot embarked on his fundraising mission last year at the age of 19, attempting to raise $1 million for research into childhood cancer. He turned 20 in July while stranded on King Island.
