Despite the title and the time frame (and the misunderstanding of the movie by other reviewers), this is not a typical war movie. This movie is really a biography and personal study of the obsessiveness and dedication that is necessary in the technological nature of warfare today. In one respect it is too bad that the movie stars John Wayne because the expectation is that it would feature a "gung ho" performance. Instead it is an amazing acting effort by Wayne as a suffering, crippled, insensitive Navy officer and author whose vision and commitment made much of the Naval air force possible. It is an excellent performance by Wayne and almost more of a "stretch" for him than Dustin Hoffman portraying an autistic "Rainman."
