A teenage pilot has become the youngest person to fly solo around the world in a small aircraft.
17-year-old Mack Rutherford landed at Sofia in Bulgaria, after a five-month journey across 52 countries.
Along the way, Mack encountered sandstorms in Sudan and spent the night on an uninhabited Pacific island.
His elder sister Zara is the youngest woman to fly solo around the world.
