Howard Hughes - if my memory and that of those who passed this on to me are correct, it has been done. I remember Syd Marshall telling me, as a very young rat in his bankstown hangar, that a fellow by the name of Goya Henry achieved the feat. Goya was responsible for quite a lot more too, if Syd was to be believed. Nothing else Syd passed on to me has led me astray so this stands up in my mind.
