AVIATION:
Dirigibles to Grace Skies Over Germany Once Again
Olaf Fritsche
Two German companies are betting that giant airships not seen since World War II can pay off in ferrying tourists and heavy objects--and perhaps even doing science. Modern materials are giving the new breed of dirigibles a big advantage over last century's zeppelins; the airships could also provide a vibration-free and steerable platform for scientists, particularly those using instruments for which a plane is too fast.
