D.6 and Dunne's descriptions 

I've now got, courtesy of the London Science Museum, a full copy of Dunne's description of some of his aircraft, part of which appeared in the letter referred to above. I've also started a new page, Dunne D.6 (though it covers all the monoplanes and possibly "The Dunne Monoplanes" would be a better name?), and I've put the relevant parts of Dunne's doc on its discussion page, together with an explanation of the purpose of the doc and comparisons of the interpretation of two standard texts.
