This film looks amazing. I saw "Flyboys", and thought it was, well, "tripe" (no pun intended) from a historical accuracy standpoint. I never realized that DR.1's were in use about a year before they actually were (the DR.1 first came into service in August 1917, about a year after the film takes place), and that every single one of them was red. The true German fighter planes of the day would likely have been either an Albatros D.V or a Pfalz fighter. The Pfalz was actually a beautiful aircraft, and would have looked great in the film.
"The Red Baron", on the other hand....looks far superior. I am so going to buy the DVD on this one.
