- Summary:
- This short nonfiction film depicts the intensive testing that goes into developing and producing aircraft propellers. It opens with the whirring or propeller blades. Animated diagrams show how the bite of the propeller moves it through the air and how the pitch determines the size of the bite. A trip through an airplane factory shows the manufacture of a satisfactory alloy. The rest of the process is painstaking hand work interspersed with dozens of careful inspections. The operation of the variable pitch mechanism and its use in taking off and cruising is shown. Then the propeller is assembled the complete job is tested for balance.

- Summary:
- "Short fictional film asking people to keep under cover during air raids. A group of English and Canadian fighter pilots report the number of German planes they have each shot down. The rivalry between the British and Canadian pilots is intense and later in the pilot's hut one of the English pilots is asked why he did not "kill" a German plane when he had the chance. He replies that the problem was "Goofer trouble". "Goofers" are seen leaving a shelter to watch a dog fight. Because these "Goofers" were in the street the pilot could not open fire without running the risk of hitting them."--British Film Institute website.

- Summary:
- "Offers revealing insights into the re-structuring of health services in London and elsewhere in Britain following the outbreak of WWII ... The film is broadly divided into three parts. The opening sequence looks at the advances made so far in the battle against sickness and disease, brought about through slum clearance, preventative and curative medicine and research. The middle section describes the re-organisation of existing services in preparation for air raid casualties, with the redeployment of city centre hospitals for emergency services and first aid, and the movement of convalescent, maternity and evacuation hospitals further out into the country. The final section uses pictures of happy, healthy children running free in the English countryside to remind cinema audiences of what Britain is fighting for."--British Film Institute website.
