RUSI specialises in research, research is about what has happened, what has happened is in the past, QED what is passed is interesting and relates to today and the future. It's called 'learning the lessons of the PAST!!!!'
The Wx3 was technically more advanced than the a/c that succeeded it at least it was in concept if not in execution, being analogue rather than digital. The question is was a simplex system with basic instrumentation better than it's analogue duplex predecessor with superb displays? The answer is that reliability trumps clever-dick design every time. Now how has the Merlin fared? What will the next generation displays have to entertain and inform I wonder?
