Submarine crews in training are instructed in the use of the Davis Escape Apparatus.
Titles read: "ESCAPE FROM TROUBLE".
Location of events unknown - somewhere in Britain?
At a training centre for submarine crews we see men being instructed in the use of the Davis Escape Apparatus. Sailors wearing skimpy pants try out their nose and mouth pieces then go inside a chamber which represents the escape compartment of a disabled submarine.
The chamber is flooded and through a porthole we see the sailors floating about inside. The men float to the surface of the water and take off their breathing apparatus. C/U of a sailor removing his goggles and looking rather waterlogged.
