...President was studying the convoy problem. Insiders knew the answer he would find. When a situation involves divided public opinion, Franklin Roosevelt likes to edge into it; only when he thinks he is sure of the reaction does he move dramatically. Probability was strong that he would exhaust every possible means of supplying the British with ships, would devise every possible shade of diplomatic approach, would allow the whole convoy problem to simmer until public opinion was definitely behind...
They are caused by high speed planes flying at 15,000 feet. Moisture forms from the plane's exhaust and also from the friction with the air. A fleet of planes would make a blanket of clouds of considerable substance, while individual planes form wisps which grow in size as they drift...
Nose-down went the P-39, trailing a white exhaust plume. Her prop, turning just fast enough to keep her Allison engine warm, began to windmill. The airspeed indicator hand began to turn-350 -400. But Andy McDonough kept his eye fixed mostly on the hands of the sensitive altimeter. Around 5,000 he eased the ship out into level flight, called the field again: "Dive completed . . . returning to base." When he landed, a doctor checked him over. Nothing wrong. Mechanics checked the Airacobra for skin wrinkles, other evidences of strain. All O.K. Andy McDonough was on his way back...
...other hand a long-drawn-out victory by Germany over the Allies is expected, what should America do then? It is generally conceded that time is on the side of the Allies; but allowing that Germany might win after an extended struggle, such a struggle would exhaust and debilitate the victor as well as the vanquished. This enervated Germany would hardly be a threat to the Americas: after its wearying death-grapple with England and France, it would have to bring the other countries of Europe to a state of subjection and non-resistance, entrench its continental position enough...
...down into carbon dioxide and water. But some lactic acid is reconverted into glycogen, which is then available for further energy release. Last week Dr. George Bogdan Kistiakowsky and five co-workers of Harvard compared this operation to that of a gasoline engine supercharger, which uses the energy of exhaust gases to pump air at high pressure into the firing cylinders. The scientists told how they followed the reconversion of lactic acid into glycogen by means of radioactive atoms ("tagged atoms") of carbon...
