Even though it will not be possible to make cars safe for the passengers against all kinds of collisions, the designs used with most success in space travel can help to diminish the risk when collisions occur. "Honey-comb" sheets which are being used more and more in modern aircraft construction, guarantee high tensile strength with little weight. They have also been practically tested in automobile manufacture. The floor of the experimental gas-turbine-driven Rover car is made of "honey-combs".' Anyone who knows the present state of research and the impetuous way in which it develops can no longer tolerate sayings such as 'It will never be possible to travel from one star to another'. The younger generation of our day will see this 'impossibility' become reality. Gigantic space-ships with incredibly powerful motors will be built, as the Russians proved in 1967 when they succeeded in coupling two unmanned space-craft in the stratosphere. One sector of space research is already working on a kind of protective screen, like an electric arc, which is attached in front of the actual capsule and is intended to prevent or deflect the impact of particles ...»
