Though only a middle man, Jung made millions off the operation. He came up with the idea to steal single-engine airplanes for transportation and charge $10,000 per kilogram, with five planes going from Colombia to California, carrying 300 kilograms per plane: this equated to $15 million per run for Jung. In the 1970s Jung was earning $3 million to $5 million per day. To avoid the need of laundering his earnings, he kept his money in the national bank of Panama.
