After creating a supply chain of materials and components that can be obtained through Canadian sources, the factory ramps up by hiring nearly 10,000 workers and providing the specialized training and equipment necessary to turn out the largest aircraft ever produced in Canada.

When the blueprints arrive on microfilm, the factory begins to train the toolmakers needed to manufacture the 55,000 components to build the first Canadian prototype Lancaster, Coded KB700 and named the "Ruhr Express".

The harrowing mission undertaken by the "Ruhr Express" is relayed all the way back to the Victory factory where workers pause to hear a radio broadcast of the Berlin attack.

Future NFB director and producer Grant McLean was the cinematographer on the documentary, later filming aboard the "Ruhr Express" on its bombing mission over Berlin.

By this point, Louis had learned how to use industrial noise along with the roaring sound of war machines, but his music was mainly martial in nature — a glorious fanfare when the first Lancaster emerged from the hangar, a brass accompaniment as the first plane struggled into the sky, and a string intervention to signal the soaring triumph of successful flight.
