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...

Three crew men were killed, four more badly hurt. It was the worst freight wreck the Pennsylvania had had on that division in 37 years...

Since coaxial cable costs $5,000 a mile, prospects of a television network had seemed dim and distant...
...pressure is obtained by a pair of small aneroid bellows; the temperature, by a bimetallic strip which coils with change in temperature; and the humidity, by a single human hair. Each of the three instruments is fitted with a needle which touches a wire, sending out a radio signal by means of a micro-transmitting set. The significance of the signals depends on the time between them. The measurement of this time interval by the operators on the ground provides all the needed information...
