Footage shot after United States battleships conclude bombardment of Japanese-held Fort Drum in Manila Bay, Philippines during World War 2. Fortified Fort Drum is seen on El Fraile Island in Manila Bay, with large gun turrets clearly visible on its top. U.S. troops and engineers had gained access to air vents on the fort top deck, pumped in oil and gasoline, and set a timed fuse. Footage shows fused explosive detonating, followed by massive explosion and black smoke as the flammables ignite.
Forests being converted to lumber industry in Northern forests of the United States. Workers sort and grade lumber with the help of machinery.

Views of Cornell University where mechanical engineer, Stanford Moss, conducted research into gas turbines as part of his doctoral thesis work in 1903. Dr. Moss later joined the staff of General Electric Company. During World War I Dr. Moss is called to Washington DC to discuss, with the National Advisory Committee on Aeronautics (NACA), development of a turbo supercharger for airplane engines. View of a biplane with turbo supercharger mounted on top of radial engine. Animated diagram illustrating workings of a turbo supercharger. Using a supercharged engine, the U.S. Army Air Services established an altitude record of 36 thousand feet. (The pilot, flying without supplemental oxygen, passes out and doesn't regain consciousness until the airplane has fallen about 30 thousand feet.)
