This video sounds like it was part of the movie tone news shown in movie theaters during the second World War.
We didn't have TV then so we got our news via the newspapers and in the movie theaters.
The Genius of Henry Ford.
This was BEFORE Pearl Harbor.
Ford's B-24 Bomber Plant at Willow Run, MI.
Henry Ford was determined that he could mass produce bombers just as he had done with cars.
He built the Willow Run assembly plant and proved it. It was the world's largest building under one roof.
