OOur heritage is the vast knowledge of our past. It teaches us what is possible and makes us develop and refine our achievements. The explorers of the poles erased the last white spots on the map, and through their heroic adventures we gained a fuller understanding of the planet we live on. The first controlled flight took off from Paris in 1852;
a dirigible invented by Henri Giffard flew 27 km using a steam engine and a vertical rudder. Pioneers of aviation then developed both lighter than air and heavier than air. The Wright brothers managed to perform the first controlled, sustained, heavier than air flight, in late 1903 in North Carolina. Aviation has made a vast difference in exploring planet Earth.
