JAJ
Whilst I agree it might appear "petty" there is a 2nd order effect here. If JN's program becomes the preserved reference for "our children & grandchildren for years to come" then there won't be anyone around to correct the errors. That is why it is so essential for the production team to get it absolutely right during the final production. I'm sure there are many around the world that believe that the Americans captured the Enigma and also tried to jump a fence to Switzerland on a Triumph whilst a POW!
Don't get me wrong, I enjoyed the program a lot. I thought JN came over well. But I do feel it's a shame that a couple of hours research by some SMEs on the finer detail via Google/Bing wasn't done - or even a screening via JN's mates. He even drank a few beers with me and a few others a fortnight ago in London and we would have given our services for free whilst downing a few real ales! I do have ~50hrs Lancs as well!
