Hovercraft RTF?
As AirUK implies, the hovercraft is another one of those fantastic British solutions looking for a problem. As a point of interest these craft were characterised and perhaps approved? more like aircraft than boats If a project were to be funded, would this be a return to flight (RTF)? I ask because most unlikely RR be interested in zero timing any Proteus engines. Is a hovercraft flying or just performing fast taxiing?
