The story of Katherine Sui Fun Cheung, who as a teenager emigrated to America where she fell in love with flying and dreamed of becoming a pilot. In the 1930s, she refused to be denied the opportunity to fly an airplane during a period in history when less than 1% of all pilots were women. Defying racial prejudices and gender biases, she earned her pilot’s license, and joined the Ninety-Nines, an all-women pilot’s club whose members included the legendary Amelia Earhart. Katherine went on to became an adventurous daredevil stunt pilot performing at air shows and competing in air races.
