First, thanks to El Reg, and to Ms Bourne, for this very interesting piece. These stories from people who were there are now, sadly, almost impossible to get.
Second, my late mum did this in Washington as a WAVE. She never really got into detail about what she did and whose codes she worked on, and we didn't think to grill her, but she could recite the alphabet backwards and always did the crossword in the morning with her coffee.
But my (virtual) hat is off to those like Ms Bourne, who did this work while in England, where everything was scarce, there was a constant danger of bombs, and the threat of invasion. Well done, ma'am, and thank you for your service!
Greatest Generation, indeed...they did more with less, and didn't complain about it.
