Please forgive the bone question from someone without FRAeS after his name; how does an aeroplane bought from North America have British "high tech internals" whereas one bought in Britain has "internals" from America? Is it some Newtonian law that I'm ignorant of?
The Orion 2000, which was up against the MR4, was to have a GEC -Marconi internal fit. The proposal was to build the aircraft in America, fly it over 'green' and fit it out at Hunting's, East Midlands Airport, who were to be the design authority. IIRC.
