One of Our Aircraft is Missing is a 1942 British war film, the fourth collaboration between the British writer-director-producer team of Michael Powell and Emeric Pressburger and the first film they made under the banner of The Archers. Although considered a wartime propaganda film, and made under the authority of the Ministry of Information as part of a series of film productions specifically aimed at morale in the United Kingdom, the story and production values elevated it from the usual jingoistic fare. Today, One of Our Aircraft is Missing is considered one of the "best of British films of the era."
A reversal of the plot of Powell and Pressburger's previous film, 49th Parallel (1941), One of Our Aircraft is Missing has the British trying to escape with the help of various local people. In the 49th Parallel, the Germans stranded in Canada argued and fought amongst themselves, while the British fliers in this film work well together as a team.
One of Our Aircraft Is Missing joins other British war films as one of the most "well-remembered, accomplished and enjoyed" realist films of the period.
