Husband-and–wife team Martin and Osa Johnson, became the first people to use aerial photography to film the wild animals of Africa and the South Seas in their natural surroundings. In 1907, Martin joined Jacob London on a sailing trip to the South Seas. His films of the people and animals of Borneo proved incredibly popular back home. Fascinated with the rugged jungles of Africa, Osa organized safaris to the region, maintained a home in tents, and hunted and fished to provide meals to the 200 native porters she hired for her  photographic expeditions. Both pilots, the couple learned to fly two Sikorsky aircraft purchased for $20,000 in 1932. They were they first people to fly 60,000 miles from Capetown to Cairo, filming roaming herds of rare animals and remote African landscapes.
