Jack Clancy was the youngest of the three Clancy brothers who burst into prominence in 1931 with the Skybaby, a single-seat light aircraft they had designed and built themselves. In the era of the Depression, it was the highly successful Skybaby which led them into aviation and an escape from infrequent and poorly paid jobs.
Bill Clancy was the talented designer of the Skybaby. He went on to a career as a noted engineer with the railways. During World War Two he played an important role in the Beaufort construction program.
Allan Clancy became a popular and respected flying instructor with the Kingsford Smith Flying School and later served in the RAAF. After the war he worked for Butler Air Transport but his flying career ended following an unfortunate accident in a DCA aircraft in 1951.
