The Royal Flying Doctor Service is a revered legend of the development of Australia as a caring nation. However, few Australians are aware of the man who founded it-John Flynn-usually known as Flynn of the Inland. Flynn, who died in 1951, is regarded by historians as one of Australia's greatest sons. In addition to creating the Flying Doctor, he pioneered the Pedal Radio, founded the School of the Air, and built bush hospitals all over the continent on behalf of the Australian Inland Mission. It is a story that every Australian should read, and its powerful drama has been captured by veteran author Everald Compton. Flynn has been his role model in life ever since he first learned about him at a bush Sunday School in 1936. His fervent prayer is that many who read "The Man on the Twenty Dollar Notes" will choose to follow in Flynn's footsteps as the future pioneers of Australia as the finest nation on earth.
