Same film was titled Hurricane, or Hurricane:303 Squadron in UK/Europe respectively if anyone wondering, the "Mission of Honor" title was for US only.
Anyways, to get another view on same story, the Polish film "Squadron 303" (in polish language with subtitles) is another to watch. Again some inaccuracies in RAF etiquette and uniform standards, that should never have happened shall we say.
