The Smith brothers had won the 1919 Great Air Race from England to Australia, and Australian aviators were now racing to be the first to cross their own vast continent nonstop. The 1,850-mile journey from point to point required navigating by landmarks over terrain where an engine failure meant landing in the outback with no hope of rescue. These early Australian flights pioneered routes that would later become the Royal Flying Doctor Service corridors, connecting isolated communities by air where roads didn't exist.
