As early as 1933, the British developed the first generation of high altitude plus crush.
The first trial and the bold trial of the flying suit, is the American Willer Berst. In the October 1934, flying players from all over the world gathered in London to participate in the international Flight competition from London to Melbourne. Webster in order to be the champion in this competition, made quite full preparation.
As early as 1931, he realized in his own flight practice that the higher the plane flew, the faster it could fly, but to fly in the stratosphere, the pilot had to wear special clothing and hats to keep warm, oxygen, shock and pressure. In June 1934, Webster invited an engineer named Goodrich to make a sealed suit out of a parachute canvas, with a helmet made of lead, costing 75 of dollars.
But when Webster in this dress to the decompression room test, just a blow up clothes burst, the waist cracked a seam, the world's first flying suit to end. At the end of July, the second flying suit was finished, immediately tested, Webster put on it sweat, had to take off. When making the third flight suit, Goodrich's friend Caulieri came up with a magic bullet. He divided the flying suit into two layers, the inner layer is made of a thicker rubber bag, which can exert some pressure on the body after being inflated, and the outer layer is made of clothing with general canvas to limit the shape of the rubber bag after being inflated.
In the August, Webster in the flying suit and made it the first flying suit of the real heaven. Subsequently, the United States, the Soviet Union, France, Germany and other successively made in the high altitude compensatory clothing. During and after the Second World War, some countries developed different kinds of high altitude compensatory suits and anti-load suits. By the 1980s, some industrialized countries developed and equipped with lightweight, air tightness and strength, easy to use flying suits.
