Titles read: "DEFIANTS IN THE MAKING".
Somewhere in Britain.
Several very good shots of women and men working in a Boulton Paul Defiant aircraft factory; women work as riveters and cover the wings with fabric. Great shots show the different parts of the plane being fitted together. Finished planes are painted black, then take their place on the tarmac outside a hangar with others. Several shots of a new Defiant plane taking off for a test flight. The test pilot turns the plane upside-down in flight. Right side up, we see a closer shot which shows the gun turret turning around.
