As is almost always the case, these films are primarily made for the entertainment of the general public and not for enthusiasts of any given persuasion. Many great British productions have taken similar liberties with historical fact. I did not like Masters of the Air at first viewing though second time around I found it better. Yes, there are shortcomings with its over reliance on CGI, the screenplay is rather lazy and the eighth episode was simply odd with the inclusion of the Tuskegee airmen - maybe that is all due to the rumoured loss of two episodes. For all that I found the portrayal of the four main characters interesting and in echoes of Band of Brothers, one of the major parts was played by a British actor - Winters/Lewis and Egan/Turner. The only thing that really grated for me was the sneering portrayal of the RAF Officers.
