"The Battle of Britain" was epic classic movie, with beautiful in-flight sequences of almost original aircraft, but usage of edited out material from this film in a documentary, is a misunderstanding. "Almost" makes a difference in this case. One could think, that Messerschmitts and Heinkels really had Merlin engines with huge radiators, because they saw it in a document... And, with due respect, special effects in the movie are not up to date. The documentary makes ridiculous usage of poorly disguised American vehicles as German ones in completely redundant scenes. But was I expecting too much?.. Well, the allegation alone, that any given "13 hours" saved Britain, should have given some hint as for seriousness of this production... By the way, the authors surely haven't heard, that in spite of "saving Britain" on 15 August, it was 18 August to be dubbed "The Hardest Day".

Despite civilian witnesses' perspective is quite interesting, but personally I was hoping to see some in-depth analysis of peculiar air raids, numbers of aicraft involved and squadron numbers... Not to mention, that it would have been nice to hear, that not only British pilots took part in that glorious day.
