The 633 Squadron is a fictional RAF Mosquito Squadron of WW II. It exist only in the movie. This is not true. The name 633 Squadron became known through a novel and subsequent movie, both of course fictional. There was and still is however a real 633 Squadron formed in 1948. It is a voluntary RAF Squadron for the flight training of young Air Training Corps cadets. I used to be an instructor with this squadron.
The key signature of "633 Squadron," a composition by Ron Goodwin for the 1964 film of the same name, is primarily in the key of E minor. The score features a mix of themes that evoke a sense of heroism and adventure, characteristic of military and aerial themes. The music is known for its bold brass and driving rhythms, enhancing the dramatic narrative of the film.
The British RAF 633 Squadron was the title and subject of a Movie starring Cliff Robertson. But I don't think you will find any historical information on this unit as it seems to be fictious. A story made for Hollywood.
World War II- RAF ( British) beware. a very sordid plot- and a Custer Brigade of the Air type of ending!
