Intrepid explorer Ethan Guo hopes to raise a million dollars to donate to cancer research. His plans hit an obstacle in Chile.

A teenage pilot, who is attempting to fly across 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.

Ethan Guo, a 19-year-old pilot and social media personality, faces legal complications after an unapproved landing in Antarctica during his solo world flight intended to raise funds for childhood cancer.
