Japanese paper balloon or fire balloon bomb in flight over field in the Pacific Theater. The paper balloon descends to the ground. Diagrammatic presentation of the mechanism of the wind velocity when the balloon is in flight.
Diagram shows pattern of air currents that carried Japanese paper balloon fire bombs from Japan to America's West Coast, during World War II. The paper bomb balloon or fire balloon unit consists of the paper gas sac and an automatic balancing and firing control device. United States Navy personnel inspects the balloon as it descends to the ground. He looks at the paper bags filled with sand which provide balance and the central payload,incendiary and bombs. He holds paper material and inspects its strength. The balloon is filled with hydrogen gas. Pressure is exerted by a rubber ring. United States Navy personnel demonstrates the various parts: demolition block,aneroid switches,jacks,blow out plugs,incendiaries and central payload. He demonstrates the balancing mechanism: Balance bags,payloads and incendiaries are suspended by T-hooks switched between the blow out plugs on the balancing ring. A man unhooks the T-hook and releases balance bags.
