New Flying Battleship (Oct, 1927)

New Flying Battleship

Huge All-Metal Biplane, Tested for Uncle Sam, Carries Six Guns and four Tons of Deadly Bombs

NEW war terrors are forecast on this page in our artist’s conception of the new giant bomber, the Curtiss “Condor” swooping down to destroy an industrial center. From its three two-gun nests machine gunners pour streams of bullets at enemy planes attacking from any direction, while the man at the bomb controls manipulates them to drop the explosives through an opening in the fuselage. With 90-foot wing spread and two 600-horsepower motors, the plane, which is all metal, weighs, loaded and manned, over eight tons, including four tons of bombs. In recent tests for War Department and Air Service officials, the huge plane took off in 200 feet and made 100 miles an hour, flying and landing gracefully. It carries 640 gallons of gasoline and has a cruising radius of 800 miles

Around-Corner Barrel (Apr, 1952)

Around-Corner Barrelis sub-machine type and shoots at 90°. It fits the Army’s M-3 and fires .45-caliber bullets at the rate of 450 per minute. It is now being used by U. S. tank crews and infantrymen.

They Harvest Seeds Of Death (Feb, 1943)

They Harvest Seeds Of Death
The pictures on this page show Royal Engineers in North Africa engaged in a job in which, as their slogan goes. “Your first mistake is your last”— clearing away land mines. Loaded with high explosive, these mines are cunningly buried, are usually set to go off only when the weight of a truck or tank presses down on them. But some of them are “booby-traps”—set to go off if a man steps on them, or even if they are not picked up in precisely the right manner. Above, a “sapper” carries a magnetic detector, to locate mines. Right, a mine has been found. Top right, result of a morning’s work.

Early Radar (Oct, 1935)

MYSTERY RAYS “SEE” Enemy Aircraft
AMERICAN and German War Departments announce simultaneously new rays capable of “seeing” enemy aircraft through fog, clouds, or dark, at distances of up to fifty miles. First tests in this country are being held at the Lighthouse Station near Highlands, N. J., by the War Department, the details of the invention being closely guarded by military police.

No larger than a penny match box is the German mystery ray machine, a highly-perfected ultra-short wave radio transmitter.

Groups of these transmitters, mounted along the border of a country and adjusted to send their “feeler” beams into the sky at a fixed angle, could be used for air defense. The 5 to 15 centimeter long beams act much like invisible light rays, and are reflected back to earth by aircraft.

Groups of ultra-short wave receivers stationed some distance from the transmitters would pick up one or more of the beams reflected. With each transmitter sending out a different type of signal, something like the interrupted signal produced by a dial telephone, and each receiver connected to the central switchboard, the distance and height of the plane could be calculated automatically and almost instantly by a machine built to interpret optical and trigonometrical formulas. With this data, air defense guns could be aimed accurately at the unseen targets.


Before radar was invented giant “ears” were used to pick up the sound of incoming planes.


TO keep pace with the great strides made by military aviation since the war—that has been the problem of the anti-aircraft sections of the artillery of all nations. The efforts of the French to do this are symbolized by this new device, by means of which ground crews listen to the approach of an enemy plane, “focus’ upon it, and determine its position and altitude. While no details have been released concerning this apparatus, which was tested in recent French aerial maneuvers, it is said to register the sound of planes 20 miles distant. Although aero-detectors have been demonstrated before, this one is interesting because of its novel construction.

Make the Most of Your Coffee Ration (Feb, 1943)

There’s Extra Cafe in that one Cup a Day

YOU’LL have to learn to be satisfied with a demi-tasse for the duration, unless you take advantage of every means to economize on coffee. Here are some tried and tested ways of getting the most out of that one pound each five weeks. Follow these valuable suggestions and you’ll get more coffee per pound than you ever brewed before, and it will be wholesome, good tasting coffee too. Better try these hints on the first pound.

Uncle Sam’s School for Sailors (Feb, 1941)

Uncle Sam’s School for Sailors

WHEN you march through the main gate of the Naval Training Station at San Diego, Calif., as a raw recruit you leave the land behind. You will spend two months learning to be a sailor before you are assigned to the battle fleet but even though you are still on dry land, things are a lot like they are at sea.

In a couple of days you will know that a floor is really a deck and you’ll not make the mistake of calling a bulkhead a wall. You will ask whether the smoking lamp is lit instead of whether you may smoke and you will be telling time by ship’s bells instead of by hours.

Paris Balloon-Homes Are Gas-Proof (Aug, 1935)

Paris Balloon-Homes Are Gas-Proof
REASONING that if balloon silk can hold gases, it can likewise keep gases out, Parisians are building balloon houses—-grim shoe-like affairs which provide safety from much-feared gas attacks.
Entire families will find refuge in each of the inflated structures. Fresh air would be pumped in through a filter which neutralizes poisonous gases, just as do filters on gas masks. Frames of wire hold the balloon silk in position when the air pump is not operating.

Magnetic Rail Gun in 1934 (Sep, 1934)

Texan Builds Novel Electric Gun

GIANT projectiles pulled at terrific velocities through powderless cannon by magnetism, leaving the barrel with scarcely more noise than that made by a .22 rifle, may set new problems for range finders.
The electric gun invented and patented by Virgil Rigsby of San Augustine, Texas, is similar to an electric motor with the field poles unrolled. Powerful magnet coils mounted end to end along the barrel of the gun are supplied with electricity by an electrical timing switch in such fashion that the magnetic pulling force is always ahead of the projectile.

OIL – Modern WAR GOD Threatens the World (Feb, 1936)

Gee, things sure have changed a whole lot since then.

OIL – Modern WAR GOD Threatens the World

Black gold, precious underground liquid, is food for the modern war machine. Deprived of it, a nation’s military campaign is threatened with failure. Will oil become an instrument to enforce peace or to cause war?

WITHIN the last few decades, oil has changed from an almost unknown and unnecessary commodity to one of the world’s most vitally needed materials. Oil, unlike nitroglycerin, has always been an innocent, viscous fluid used for lubrication and fuel. But harmless petroleum, like Dr. Jekyll, has undergone a startling transformation. Oil may yet be the means whereby the flaming torch of war is carried across the world.
