From a U.S. Navy training film "Special Conditions of Flight" on the working of airships. Special conditions of flight are explained. An airship in flight. High winds and snow create problems for flight. It also creates problems for ground handling of the airship. The airship lands. Ground crew rushes towards it. 'US Navy' written on the airship. Men at work. Special masts are erected on the ground to handle airships during bad flight conditions. A crew inside the airship. The airship in flight. An instrument panel. A rudder man at the controls of the airship. Guided by careful weather forecast, the airship's operations are conducted.
Film about the conditions at German concentration camps in Europe during World War II. Affidavits by George C. Stevens and E.R. Kellog that attest to authenticity of scenes in the film. A map of Europe depicts the location of Nazi concentration camps.
Surgical instruments in an operating theater.Microscopic views of bacteria, including those causing lockjaw and gangrene, respectively. Views of streptococus and staphylococus. Surgeons scrub before undertaking surgery. Cartoon animation of Bacteria and skin.
Surgeon is seen scrubbing hands and arms for five minutes before performing surgery. When finished, he sneezes, but does not return to scrub and clean his hands again. Animated cartoon shows bacteria surviving the scrub brush bristles and remaining in place. Animation shows additional streptococcus bacteria descending onto surgeon's hands after doctor sneezes. The bacteria present through the scrubbing, and the new streptococcus bacteria talk to one another (voiced by Mel Blanc). The bacteria are isolated by surgeons rubber gloves before he begins patient surgery operation.
Surgical theater. Patient brought in. A patient to be operated upon. Doctor with contaminated hands accidentally spills instruments and cuts his rubber glove. Discards only one instrument although unsure which one actually caused the cut glove. A contaminated instrument remains and is used in the surgery.
Surgery patient in postoperative recovery is visited by U.S. Navy doctor who examines him and concludes he is doing well. (But patient has unrecognized infection, resulting from accidental contamination of an instrument during surgery.) Animated cartoon illustrates how infection progresses into blood poisoning. Shows bacteria awaking inside human body cavity and in a pool of plasma. Shows animated bacteria dividing and multiplying in the plasma. The bacteria talk to each other in the cartoon and refer to each other as poison (voiced by Mel Blanc). The bacteria play and dive in plasma pools as they multiply. Cartoon shows leukocytes coming out of capillary wall and moving through the tissue. It approaches a group of bacteria and devours them, then enlarges. Many leukocytes are seen consuming bacteria. Cartoon shows an abscess beginning to form, and then shows a streptococcus bacteria. It multiplies and plays in pools and slides inside the body, playing and laughing fiendishly. Chains of streptococus bacteria enter a capillary partially blocked with clotted blood, and then into the blood stream of the human body.
