Final process in making fuel tanks for U.S. combat planes.

Final process in making fuel tanks for U.S. combat planes. Under the careful eye of an inspector, a freshly painted auxiliary tank passes through a tunnel of infra-red drying lights on the final production line of a U.s. war plant. These fuel tanks increase the flying rang of U.S. combat planes many miles. Hung from bomb releases on the plances, the tanks are used only once, and dropped when they are empty.
