Hmmmm
Overall, after part one, quite impressed, however I was a little alarmed to see, during the opening credits, Bf110's (then a daylight fighter) bombing London in 1940 at night, and worse, cannon-armed Spitfires as night-fighters, carrying 1944 invasion-stripes!
Happily the artistic-license of the opening credits was not representative of the period accuracy of the rest of it, which at first blush, was good. Perhaps this will become a series extending into 1944/5 in time?
