Ethan Guo, a 19-year-old pilot, is on the verge of breaking a world record by becoming the youngest person to fly solo across all seven continents.

Flying a modified Cessna 182, a propeller-powered aircraft, he touched down in Mumbai during the night of August 6 and 7, as part of his global journey that began in Geneva, Switzerland. But his mission extends beyond just flying: Ethan is on a quest to raise USD 1 million (Rs 8.22 crore) for childhood cancer research and to spread awareness about the disease. Upon his arrival in Mumbai, Ethan met with this reporter to discuss his cause.
