I find this rather hard to believe. It doesn’t seem practical, nor does it seem that 40 people would be neccessary to man 3 torpedo tubes.

Sunken Pillboxes Guarded Jap Coast
Japan’s anti-invasion line went out under water at Tokyo Bay. Pillboxes were built into the hulls of sunken ships and equipped with three torpedo tubes and a sound detector. Each pillbox held 40 to 50
men who were relieved every 10 days. Food was canned; oxygen, bottled.

Realistic Moving Targets Train Antitank Gunners
Constructed of wood and cloth, and equipped with wheels and ground skids, dummy tanks are drawn across open terrain at a speed of twenty miles an hour to give practice to British antitank-gun crews. Pierced by numerous direct hits, a dummy tank is pictured at the left after practice.

What could I possibly add to this?

Portable Sound-Detector Units Made for Airplane Spotters

A self-contained sound detector, easily carried and operated by one person, makes it possible for individual aircraft spotters to hear approaching aircraft through a set of earphones. When the low-pitched sound is picked up, the spotter slowly turns his body until the sound is loudest. He is then facing in the direction of the plane and can orient his binoculars. The headpiece of this detector consists of earphones topped by a concentrator. Made of thermoplastic material, this is molded to a parabolic curve and contains crossed perpendicular veins which sharpen the aural focus on a sensitive microphone. Amplification is supplied by a three-tube unit slung over the spotter’s shoulder and housed in a case smaller than the usual gas-mask container. A volume-control knob regulates the sound in the earphones to the watcher’s comfort. Special filters eliminate noises other than those of a plane.

Could You Be A Hero? (Aug, 1957)

This is a pretty funny article about what gives a man courage and what makes him a hero. The real gem however, is the Courage Quotient Quiz. This asks a series of ridiculous questions that seem to have nothing to do with “courage” or “heroism”.

Here are a few examples of statements from the quiz that a man with courage would agree with:

  • Desk work is more for a woman than a man
  • Any man should love camping and hunting
  • I’d rather read a detective story than a humorous story

Here are few statements that reflect poorly on your courageousness:

  • A totalitarian system of government is more efficient
  • After most wars, the U.S. came out the loser in the peace treaties
  • A cowboy movie is more interesting than a good love story

The one thing I can’t understand is why is a detective story courageous, but a cowboy movie is not? Would it be the same if it was a detective movie and a cowboy story?

Take the test for your self to find out if you’re a real man or a whimpering pansy.

Could You Be A Hero?

By Harry Kursh

Your reactions in the face of danger are based on personality traits you may not even be aware of.

(Editor’s Note: Before reading this article we suggest you turn to page 55 and take the Courage Quotient Test to rate your own potential for being a hero when confronted by danger.)

ONE foggy morning last November, 57-year-old Jonathan Kruger stopped to chat with his daughter on a street in North Bergen, N. J. Suddenly, he looked up. He heard the sound of a plane flying too low. Then he saw it. The plane was headed straight for a tall radio tower. In a flash it was a fiery mass bouncing off the tower into the side of an apartment house.

“Night Glasses” Train Soldiers To Fight in the Dark
For practice in fighting in the dark, cadets in a British officers’ training unit wear special “night glasses” during daytime maneuvers. Fitted with dark lenses, the glasses reproduce the visibility conditions that would be encountered at night. In this way, the young soldiers learn to recognize the landscape as it appears in darkness, and acquire skill in taking “pot shots” when they cannot see their rifle sights. In the photograph above, several cadets are using the glasses which turn day into night.

Tricycle” Trains Army Bombers

Perched on an odd three-wheeled framework of metal tubing, a U. S. Army pilot and his bombardier are pictured above at Riverside, Calif., getting in some ground bombing practice with an electrical machine said to simulate actual bombing conditions. A falling plumb bob plays the role of a bomb. Note that the bomb sight, a closely-guarded Air Corps secret since it is reputed to be the most accurate in the world, is covered with a hood to hide it from the prying eye of the camera.

Electric Cannon Uses No Gunpowder

SILENT guns sending their whistling messengers of death into the sky at speeds far beyond those now attained by powder-driven shells seem likely for the next war, using for propulsion magnetic fields so powerful that when they are short-circuited they produce miniature earthquakes.

Dr. Kapitza, F. R. S., working at the Cavendish laboratory of Cambridge University, England, in his attempts to disrupt the atom has produced magnetic fields so powerful that they “explode” the coils that produce them. This man has finally revealed the secret of the magnetic gun so long anticipated by ballistic experts. Dr. Kapitza accomplishes the electric firing of a shell by short-circuiting powerful dynamos for periods of one one-hundredth of a second.

This is insane. I don’t trust myself to make an improvised shelf, let alone a gas mask. Plus, a gas mask that requires you to hold your nose while breathing does not exactly inspire confidence.

Civilian Designs Simple Gas Mask
With the threat of gas raids hanging” over more and more cities in Europe, the demand for gas masks in many communities far exceeds the supply. To provide some sort of gas protection in case of an emergency, an ingenious Scandinavian inventor has designed the improvised mask shown at the left. It consists simply of a hollow wooden tube and a cloth bag filled with chemicals. Air purified by the chemicals is sucked into the mouth through the tube, while the nose is held shut with the thumb and forefinger of the hand holding the mask.

Why Don’t We Build… Underwater Tanks

We need such a weapon for beachhead invasions … we have already solved its technical problems.

By Frank Tinsley

EVEN at the outset of our World War II campaign of island conquest in the Pacific, it became evident that some form of armor was needed to spearhead landing operations. The old technique of wooden landing barges and surf-spattered Marines was obviously inadequate. To pit unprotected flesh and blood against an array of underwater obstacles, mines and wire entanglements, backed up by well concealed and heavily bunkered machine-gun nests, mortars and artillery, was a murderous waste of expensively trained men.

Rack Protects Food from Poison Gas

Supplies of food and drink can be protected from contamination by poison gas in case of wartime air raids by a novel and inexpensive device developed by M. Jaffe, a British inventor living in Liverpool. Food is placed on a raised wire platform and covered by an inverted mixing bowl, bread box, roasting pan, or other nonporous kitchen utensil. By means of two long wire handles, the covered food is then lowered into four or five inches of water standing in a basin or in the kitchen sink. The water forms a perfect air lock inside of the improvised food protector, making it impossible for gas fumes to seep in. With the device, it is said, one minute is sufficient time to protect a supply of food which could be consumed without fear of contamination or pollution after the danger of the gas raid had passed. Larger units could be used for protecting food in hospitals and other institutions.

Lead-Lined Suit specially designed to protect against radioactivity in an A-blast, was designed by Leo Pauwela of Los Angeles and is modeled here by his son. “If it doesn’t land on us, we’re safe,” they say.

Also, they claim the atomic reactor reaches tempuratures of 600 billion degrees. Does this seem a little high to anyone else?

The U.S. is working on plans for a satellite base, Defense Secretary Forrestal reveals. Take a long look at this man-made moon—and learn how it may rule the world.

EVEN Jules Verne would be amazed at the latest activities of the U. S. Department of Defense. Secretary James Forrestal disclosed recently that his department is working on a “satellite base” to revolve around the world like a miniature moon, as a military outpost in space.
