...procedure with the large battle cruisers will be somewhat different. The Hindenburg lies in 66 ft. of water, on an even keel, with its upper works projecting above water. Divers have examined it. Seaweed has completely mantled its lower surfaces. The interior is fairly well intact, even to champagne bottles in the wardroom. Barnacles and muscles encrust the sides; mud and sand have drifted in. The divers will be called upon to shut the seacocks, to close all the openings with metal patches and concrete plugs. Then a six-foot pipe will be sunk through the decks; pumps having...

...devices for blind flight, which-allowing pilots to keep their course without reference to land marks -will permit them to fly high above such storms as caused Pearson's death. One device is a lateral level indicator., showing whether the plane is flying on a level keel or not, even when there is no horizon or land to refer to. A pendulum or a bubble level will not correctly indicate a true vertical line, when subject to the air disturbances a plane must inevitably meet. A spinning top, once vertical, will stay with its axis vertical no matter...
...entering a fight blind-folded;" whereupon to prove his point, General Patrick proceeded to show some terrifying pictures of the bombing of the battleship Alabama. Exactly six minutes elapsed between the moment when the 2000 lb, bomb struck the deck of the doomed ship to the time when its keel disappeared beneath the sea. And to show how much the art of air-offence has improved, nowadays three air-planes can drop in one fight as many tons of bombs as were dropped on London during the entire war. Indeed, the most extraordinary event in the twentieth century has been...
Navigation. A giant submarine cruiser of more than 7,000 tons, invented by Prof. Oswald Flamm, of Germany, has been built in model by the Augsburg-Nürnberger Machin-fabrik. The boat is heartshaped, point upward, with the keel in the groove of the heart, like an inverted V. The principal advantage is rapid and even submersion, the stability depending on the form and the distribution of pressure. It can submerge in 30 seconds without turning a degree, can cruise 20,000 miles and develop a speed of 23 knots an hour. It is 525 ft. long...
