One omission is at the end of the film, when casualties are listed. The film does not mention losses by the "Corpo Aereo Italiano", an Italian expeditionary force that took part, nor is its participation mentioned during the film. One anomalous entry in the list of pilots who served with the RAF is a Palestinian pilot described by the credits as "Israeli", even though the State of Israel was only created in 1948. This referred to George Goodman, an ace born in Haifa while Palestine was under British administration, who was killed in action in 1941. There was no attempt to recreate tracer rounds.
