The Greatest Air Race is presented and narrated by astronaut Andy Thomas as he embarks on a trans-continental journey to retell one of the world’s greatest aviation stories. In 1919, four Australians became the first men to fly across the globe. They flew from London to Darwin in a rudimentary plane made of canvas, wire and wood, sitting in open cockpits with only a compass for navigation. They completed the 11,000 mile journey in 28 days.
