Character mistake: When Dutch is at the main gate to report for duty, he addresses an Airman as Sergeant. In the time period of this movie, an airman wearing three stripes would be an Airman 1st class.
Character mistake: Richard Thorp is Henry Maudslay, who got killed on the raid. However, at the end of the film, in the mess, he is patted on the shoulder by Stanley Baker. Big error.
