This is actually a very good movie with a lot more truth behind it than one might imagine. As this is a British movie, it was a very smart marketing idea to have a famous American actor, George Peppard, and a famous Italian actress, Sophia Loren, co-star in it. This way they could say "Starring (insert famous British actor name here)" when marketed in Britain, and advertise it as "Starring George Peppard" and "Starring Sophia Loren", when marketed in the U.S.A.and Italy respectively. This gives the makers of the film a much larger audience than just Britain. George Peppard and Sophia Loren have significant roles, but are not the stars of the movie. Details like portraying Hanna Reitsch and having accurate, and very good special effects make this far better than most World War II movies. Especially since most of the stars of the movie don't survive. If you enjoy historical accuracy, a well thought-out plot, and the unexpected, then I think you will find this movie a top-notch production and well worth watching. Without spoiling the ending, I will tell you though that the Gemans did not win the war.
