...place. On the control board-called "the Christmas tree" because of its numerous red and green lights-lights flashed, showing Prien that the air induction valves, which carried air to the engine rooms, were closed and watertight. Down planed the Squalus. As the depth gauge showed nearly 50 ft., she began to level...
...rescue chamber came within 150 ft. of the surface on its final trip up, the lower cable fouled on its winch. For three hours and 45 minutes Lieutenant Naquin and seven men had to revise their calculations on the probability of death, while around them divers worked desperately in the darkness. Finally the jammed cable was cut and the bell hauled up foot by foot. At 12:38 a.m. of the second day the U. S. Navy had rescued its living. Below, in the hull of the deep-diving Squalus, 26 corpses slept...
Last week a spectacular and unprecedented accident happened to the University of California's famed Lick Observatory, first of the big mountain-top star-stations, perched on triple-peaked, 4,209-ft. Mt. Hamilton. An army attack plane, flying on instruments through fog, hit the main observatory building like a rifle bullet aimed at a bull...
...year contract before expropriation. Last month Senor Foianini arranged two important treaties that made their extensive exploitation possible. Argentina agreed to permit transportation of Bolivian oil across her territory provided the expropriated fields were not returned to private owners. Paraguay agreed to give Bolivia: 1) a 325-ft. pipeline right-of-way across the Chaco battlefields to the Paraguay River; 2) two free zones for a refinery and a shipping point; 3) a 3O-year monopoly to supply Paraguayan oil requirements; 4) freedom from taxes and levies on shipments from the Bolivian refinery. Since Paraguay uses little oil, main purpose...
...Edward P. Warner were two new wind tunnels which are now in operation. In both, NACA engineers work under a pressure of several atmospheres, like sand hogs or divers have to be decompressed before going home at night. In one, studies can be made on fixed models of 19-ft. wingspread in winds of more than 250 m.p.h. In the other a model can be flown as in free air, operated by remote control from a tunnel cockpit. Control is achieved through fine wires to electromagnets in the ship...
