...Langmuir, having studied ballistics formulae, showed that if the botfly flew at 800 m.p.h. the wind pressure against its head would be 8 Ib. per sq. in., "probably enough to crush the fly." The power needed to maintain such a velocity would be 370 watts or about one-half horsepower -which is, as Dr. Langmuir exclaims, "a good deal for a fly!" Also, the fuel requirement would be so high that the insect would have to consume more than its own weight of food every second...
...Douglas four-engined super-airplane. They agreed to pool their knowledge and to share the expense of development. Meanwhile, they also agreed to a limitation of airliners: pending the result of the joint effort none of the lines would put in service ships of the projected size (43,000 Ib. to 75,000 lb.). While they had their heads together, T. W. A.'s Captain Daniel W. Tomlinson was working on plans for substratosphere flying for T. W. A.'s President Jack Frye. At the same time Seattle's Boeing Aircraft Co. was building the great high...
...tree in the juryroom and as a special favor they were allowed to speak to their families. Their mail was carefully censored. They were not allowed to see The Life of Emile Zola because of the courtroom scenes. But in 16 weeks they had gained a total of 220 Ib...
...trucks and the lower portion of the car's body. Result is a full-size passenger coach whose floor is 30 in. above the rails instead of 4¼ ft.; whose roof is u ft. instead of 14 ft. high. Weight, if made of duralumin, is 50,000 Ib.-40% less than present streamlined cars...
This week the 3,663-ton North German Lloyd freighter Dessau docks at Houston, Tex. Under her decks are 486 empty steel cylinders to carry back to Germany the first installment of U. S. gas. At 2,500 Ib. per sq. in. pressure, 5,600 cu. ft. of helium can be compressed into each cylinder. In the U. S. helium for medical treatments (asthma, croup), deep-water diving, laboratory experiments, is shipped 200,000 cu. ft. at a time in cylinders 40 ft. long, 4 ft. in diameter which travel four to a flatcar...
