Vanderbilt University student Logan Tinley, 19, has been a licensed pilot for just over a year -- but he's already become the youngest American to fly around the world solo in a single-engine propeller plane.
Logan was inspired by family friend Ethan Lassiter, 8, who is battling pediatric cancer. While Ethan is currently doing well, Tinley told news outlets, "I just remember sitting down and thinking to myself about the kids who could not get good treatment."
That's when Tinley founded the Ascending Frontiers Pediatric Cancer Foundation, and planned his trip around the globe to raise both money and awareness. His ultimate goal is $500,000, of which he's reportedly collected $40,000 so far.
