An American teenager who is trying to fly solo to all seven continents in order to raise money for cancer research, has been arrested after landing in Antarctica without permission.

Authorities in Chile allege Ethan Guo, 19, broke “multiple national and international regulations” after changing a flight plan without informing officials and landing in part of the Antarctic where it has a territorial claim.

“I want to become the first person in history to fly solo to all seven continents in a small aircraft and raise $1 million for cancer research,” Mr Guo writes on his website.

He adds: “In 2021 my cousin was diagnosed with cancer. I admire him. He inspired me to take life more seriously and join the fight against cancer.”
