Hopefully, it's not a lot of "WE SPENT A LOT OF MONEY ON THIS CGI, AND BY GOLLY, WE'RE GONNA USE IT!" type stuff. As cartoon pile-its we know instinctively the correct bank of a plane in any given turn, the correct distances between planes, and the correct perception of speed, ALL areas where Hollywood has consistently got it wrong. Let alone historical inaccuracies of putting the wrong equipment from the wrong era/theater in the wrong hands. BUT... there's a fine line between a compelling story and a historically accurate snorefest.
