The film's closing epilogue states: "By the year 1951 all the Czechoslovak RAF airmen were released from the labor camps. But they remained outcasts for most of their lives. It was only in 1991 that the survivors were rehabilitated and recognized for their wartime service."
A significant number of the Spitfires shown are later marks than would have been used in 1940, as is evidenced by their larger (and subtly differently shaped) vertical stabilizers and two underwing radiators. (Mark I and Mark II Spitfires would have had only one underwing radiator under the starboard wing, supplemented by a much smaller oil cooler under the port wing.) Also, the scenes in which Me109's appear show aircraft with unusually large chin cowling, indicating that they were probably made in Spain under license after the war (and equipped with something other than the period-correct Daimler-Benz engine that an Me109 would have had in 1940).
The RAF-commissioned officer conducting the life raft training is shown wearing "shoulder flashes" with an embroidered eagle. These were not worn by commissioned officers, only by Warrant Officers and below.
