The Southern Cloud, registered VH-UMF, was one of 5 three-engine Avro 618 Ten aircraft flying daily airline services between several Australian cities for Australian National Airways in the early 1930s. On 21 March 1931, the Southern Cloud departed at 8:10 AM from Sydney for Melbourne. Onboard were six passengers and two crewmembers, including pilot Travis "Shorty" Shortridge.[2] Weather conditions en route were hazardous and much worse than predicted. The aircraft never reached its destination and disappeared.[3]
