At the end of the war, Wallis returned to Vickers-Armstrongs as the Head of Research and Development. Under his leadership, the company was at the cutting edge of aeronautical engineering. In order to conduct his research, Wallis and his team constructed the Stratosphere Chamber which was the largest in the world at that time at almost 20,000 square feet in size. It was constructed near the famous Brooklands racetrack at Weybridge.
As the Cold War became the new challenge, the Chamber was used to simulate impacts on aircraft travelling at 70,000 feet which was the target altitude for Wallis’ planned new supersonic plane. By building a large refrigeration plant, the Stratosphere Chamber was able to supply extremely cold liquid methane at each of the four corners of the facility. It was an immense enough facility that even the largest fuselages and cockpits could be accommodated, and was sophisticated enough to test impacts at temperatures as low as -60C and at an air density one-twentieth of that which is found at ground level. With its extreme cold capacity, the Stratosphere Chamber was also able to experiment with naval guns operating in frigid conditions, as well as fishing vessels operating in blizzards in the North Sea.

The white umbrellas strung across the square offer an attractive spot of shade in what can be strong sunlight and heat.
