In this series of the Retro Time Machine, we travel back to the 1940's and discover how teenage girls kept war materials rolling in factories all across America.
A young blue eyed blond is instructing elders to become inspectors and machine operators in a big war plant. Outside you can hear the faint hum of powerful machinery. Another girl in the same factory is an accomplished electrician working on a Vega Ventura Bomber.
These were the "soldiers of production" in war plants across America in the 1940's.
