The demand went in to the appropriate M.U. (Union Jack is now convulsed with laughter if he is reading this).
Au contraire, Danny. I was aware that bomb scows were used for transporting armaments from shore to flying boats and amphibians but, until I did a quick shoogle with google, I was unaware of the more precise details of their history. Worth a look - there are lots of pictures, and everything from the award of a posthumous George Cross to a very brave man trying to help one of his comrades after a Sunderland exploded at Singapore to the court case of an Australian accused of stealing a bomb scow in the Northern Territory.
By and large (a good sailing expression), I am drawn to the conclusion that it was just as well that your empire was not increased by the arrival of such a vessel, despite your worthy attempts to prepare for its arrival!
Perhaps a former member of Coastal Command or the Marine Branch can come up with some more personal reminiscences of such craft.
