Alan Cobham and mechanic A.B. Elliot departed the River Medway, England, on a survey flight to Australia in De Havilland DH50J G-EBFO. The photo shows the aircraft on the beach at Darwin being prepared for lifting to fit the wheels. The signwriting on the side of the aircraft reads 'SIR CHARLES WAKEFIELD / FLIGHT / TO AUSTRALIA / DH50' (Wakefield was the flight's sponsor).,
