A teenage pilot, who is attempting to fly all 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.

Chilean prosecutors say American influencer Ethan Guo, 19, broke “multiple national and international regulations” by changing his flight plans without prior notice, landing on a part of Antarctica where the South American country maintains a territorial claim.

CNN requested a comment from Guo, whose lawyer on Sunday said the young pilot had experienced “complications” while flying.

Guo, whose website states he is trying to raise $1 million for cancer research by becoming “the first person ever to fly to all seven continents solo,” has broadcast his continent-hopping journey since last September to more than a million Instagram followers.

His last post, on June 23, documents a flight over the Philippines.
