Hi Nico,
I concur with the comments of the others ……. a tremendous effort …..a substantive compilation putting the work and involvement of so many into historic context – an epic time of human endeavour which is now so largely forgotten. Well done.
However, the text may still require some proof reading – at least the couple of areas with which I am familiar contain misquotes and misspelt names – As mentioned by Jason Dechaineux, Bert Hinkler was not, as you wrote, a Yank, but a Queenslander (ie/ not American but an Australian). Also Flt Lt G.H. Stainforth, a long-time member of the High Speed Flight (part of an illustrious career as an RAF test pilot) is referred to in your text as Stainford – a quite different name.
Ref. for part see “Supermarine Aircraft” C.F. Andrews & E.B. Morgan. 1981,ISBN 0 85177 800 3. Reprinted 1987.
Best Regards, B. Stainforth.
