GUN POWER will make history when the Allied grand fleets force a showdown with the elusive Japanese Navy. The big rifles that speak from the turrets of our men-of-war are the most powerful instruments of destruction ever used at sea. Arthur Grahame tells how they evolved from the simple brass tubes that were the first naval artillery, 500 years ago.

ON PAGE 72 of your August issue, you give a vision-range formula that has been worked out by the Clipper captains of Pan American Airways. The formula is to multiply the square root of the plane’s altitude by 1.225, the result being the distance that a pilot can see.

SUPPOSE you got tossed out on the ocean from a torpedoed ship or a plane that couldn’t make it home after a bombing raid. Do you think you could find your way to land? You stand a good chance of doing just that if you have with you on your raft a watch in a waterproof case (or, better still, in a transparent, waterproof rubber sack that can be kept closed) and two charts, one of the heavens and one a navigational base chart of the world, and both drawn to the same scale.

TALK all you want about airplanes and electronics and motor transport —the part of this war effort which really rates a shout of amazement is the role played by the American railroads. The iron horse, which plowed the plains and spanned the mountains, was not what he used to be.

STEWART ROUSE
YEARS ago, our Army developed the first aerial oxygen equipment, along with its first high-altitude planes. This “free-flow” system worked well enough in the earlier days of military flying; the oxygen was fed from the regulator into the mask, and the pilot turned a handle to increase the flow as he gained altitude.

OFF Ford assembly lines has come a tank engine that our fighting men hail as an Axis beater. It has what it takes to triumph in armored warfare—speed, dependability, and “zip.” What’s more, its compact construction makes it simple to service, and mass production is possible with a minimum change of available machinery.

WHEN the order, “Prepare to ditch,” comes over the interphone system of one of our big bombers, 30 seconds may mean the difference between life and death for the crew. For that warning, sounded by the pilot, is notice that the big land plane is being forced down on the sea, and 30 seconds afloat without seaplane landing gear may be all that can be expected even under the most favorable conditions.

DON ROMERO
WHEN Mark Twain said that everybody talks about the weather but nobody does anything about it, he did not envision the spectacular advances that lay ahead in meteorology. Nor did he foresee the day when the airplane would be as common as the horse and buggy; and when, to every pilot who took his plane into the air, the weather, instead of being a subject of casual conversation, would be a matter of life and death.

INFRARED DE-ICING RADIATORS are proposed by J. D. Altemus, of Roslyn, N. Y., as a new solution to one of aviation’s most insistent problems. Mounted on the nose and propeller hub, the radiators would focus their beams on the propeller blades and leading edges of the wings to keep them above icing temperature.

SAY “Good morning” to the first 15 people you meet, and at least one of them probably will have to guess at what you said. Or, if all of them hear you clearly, you may be the one in 15 who has defective hearing. That, according to a recent estimate made by the New York League for the Hard of Hearing, is the average ratio of deafness, whole or partial, in the United States.

Instead of discarding the lamp or putting up with poor light, specialists at the General Electric lighting research laboratories advise, simply make an extension base and use a shade with better proportions.
