With those words French Secretary of State for Transportation Pierre Billecocq co-signed the historic 1973 treaty committing France and Britain to support the construction of a 32-mile train tunnel under the English Channel. Plans to link the two nations by "chunnel" had graced the drawing boards of imaginative engineers for nearly 200 years; French Engineer Albert Mathieu's 1802 design shows a coach-and-four trotting through a candlelit tube with ventilating pipes reaching above the waves. But whenever the 19th century pipe dream threatened to come true, Britain got skittish. A characteristically insular reaction came from...
...home of Ishpeming, Mich.-the pilot told him to learn to build planes, not fly them-Johnson has lived aviation. After studying aeronautical engineering at the University of Michigan, he landed a job with Lockheed in the Depression year of 1933, largely on the basis of an impressive wind-tunnel analysis he had made of a model of a forthcoming Lockheed plane; the young graduate recommended a twin tail for the new all-metal, twin-engine Electra, Lockheed's first successful passenger plane (Neville Chamberlain used it to fly home from Munich). Reason: a single rudder offered inadequate control...
Underground Maze. Archaeologists once thought that Bronze Age people got their metals largely by chipping away at surface rocks; at most, they would tunnel only a few dozen feet. The newly discovered mine shows that the Bronze Age miners were far more skilled and adventurous than that. Located at the base of towering, 2,200-ft. red sandstone cliffs, the mine contains a complex, multilevel network of some 200 shafts and galleries. Although only a small portion has been excavated so far by Rothenberg's team, which included ten West German coal miners, the maze apparently reaches hundreds...
Durano said that there would be "no digging" in Radcliffe Yard, but that the tunnel would be "bored" 20-40 feet under the surface, in no way endangering the foundations of any buildings. He estimated the cost at $35-45 million...
