The de Havilland Vampire jet planes seen in this film had a surprisingly short active service life with the RAF, lasting only from 1946 to about 1960 before being replaced by more sophisticated planes. By the time this film was made they were already considered old fashioned, especially compared to the more advanced Russian MIG jets and plans were being initiated to replace them with the next generation of jet fighters. However some other countries like the new Zealand Air force continued using the planes until the 1970s.
Andrew Keir and Duncan Lamont are often credited with being in this, but are nowhere to be seen in the final print.
