TED-Ed: Can you solve the airplane riddle? - Judd A. Schorr

A professor designs a plane to fly around the world nonstop but faces a fuel capacity issue. To solve this, he uses three planes that can transfer fuel midair. The planes coordinate their journey, with one plane returning to refuel while the others continue. The professor's plane reaches the halfway point, and the other planes meet him to transfer fuel, allowing all to complete the journey successfully. The experiment concludes with a promise of future commercial flights.
