Hot air balloonists are adventurers: they never know where the wind will blow them or where they will land. They spare no effort to discover the world from above in their balloons. Phil and Allie Dunnington are among the best balloon pilots in the world. The series “High Flights” accompanies them on their journeys to the fascinating landscapes of the earth. Their special way of experiencing the world brings them breathtaking views, dramatic landings, foreign cultures, and unexpected encounters. For balloonists, Mongolia is a dream. Endless steppes and vast deserts promise unimagined high flights. Four international balloonist teams have traveled to the Central Asian country to experience this. The expedition, led by Phil and Allie Dunnington, takes them to new destinations, to places where no balloon has ever flown before.
