If I had been president, I would have come out and declared: "Nothing there, ever! This place stays as it is. We make a big place there where people can pray about the errors we have made that those two towers had to fall."

Everybody in Germany was for the -German cause. But then, after the war ended, when I heard the first Glenn Miller sound on the radio and these fantastic American music makers, I turned into a jazz fanatic. They called me Benny, after Benny Goodman. So, all of a sudden, the eyes of young Germans were opened to America - everything American was absolutely at the top of the list.

1973 was the first gasoline crisis in the world. That year, I designed the first aerodynamic truck, eating 40 percent less fuel. I put it on exhibit everywhere. It was 30 years ahead of its time. Nobody is building it today, and everybody still has problems with their boxy cars and trucks eating up fuel.

I'm a very peaceful man. In the '80s, I was the chief designer at Thyssen, one of the biggest companies in Germany. But when they asked me to design armored vehicles, tanks, and submarines, I quit overnight.

I learned to ask myself questions like: Why is something made the way it is? Why does a motorcar look like it does? Is it right or wrong? What is an airplane? Why is it shaped like that? Then, later, I became a diver and studied subaquatic life and the streamlining of sharks and manta rays. Any fish is superior to the shapes we humans have invented - and unchanged for 250 million years, imagine!

You see, if you are 30 years ahead of your time, you will always have difficulty speaking with the bosses in the industry. They are too conservative.

The earth is round, all the heavenly bodies are round; they all move on round or elliptical orbits. This same image of circular globe-shaped mini worlds orbiting around each other follows us right down to the microcosmos. We are even aroused by round forms in species propagation related eroticism. Why should I join the straying mass who want to make everything angular? I am going to pursue Galileo Galilei's philosophy: my world is also round.
