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.
