One project Dad worked on was on bringing the Camco V-Liner to the UK. In the process of development it appeared on BBC1 Tomorrows World - presented by Raymond Baxter. The following is an extract from Flight International Sept 1968. The Cameo V-Liner ONE OF THE MOST UNUSUAL aircraft to appear in recent years, the Cameo V^Liner "aerial advertising and information dissemination aeroplane" is taking shape at Slingsby Aircraft Company, Kirkbymoorside. This firm, which has undergone a considerable transformation since controlling interest was taken over three years ago by a group of Yorkshire businessmen, has been selected by the American organisation Cameo (the Central Aircraft Manufacturing Company of Washington, DC) to build a revolutionary aeroplane designed specially for the purpose of aerial advertising, traffic control, geomagnetic survey and a number of other possible applications. (Sensor, April 18.) The V-Liner is a development of the airship advertising (principle, which is fast becoming uneconomic because of high capital and running costs and excessive manpower demands. Market surveys are said to reveal a big potential demand for an aircraft of this type, especially in America and Canada, although aerial advertising is illegal in Britain. The V-Liner (so called because of the shape of the structure) is being pushed along under a four-year, $1.5 million development and design programme in America, Canada and Britain. First flight is scheduled for late 1969. The aircraft has tandem wings, spanning 69ft and joined by a V-sectioned alloy-tube structure 378ft long. Power is supplied by two Rolls-Royce Continental 375 h.p. piston engines mounted over the front wings, while an auxiliary 100 h.p. engine over the rear wing provides power for the electrical display lighting.
