...state legislature), led by Rep. John J. Toomey, chairman of the powerful Ways and Means Committee, had fought to put it there. The veto had been effective, or so it seemed, and the city's representatives were determined to keep it part of the law. This was Cambridge's shield. The city--the Administration, the threatened neighborhood--feared the highway, but, protected by the veto, did little to organize a permanent political opposition...
...fails to set off the warhead's conventional explosive, it can damage electronic components or cause sufficient changes in the critical shape of internal cavities within the warhead to prevent a nuclear explosion. In addition, the heating of the ICBM's exterior may so damage its heat shield that the missile would burn up upon entering the atmosphere...

...South Pole, the South Pole the North. During these reversals, scientists theorize, the intensity of the earth's magnetic field actually decreased to zero, then built back up with opposite polarity. During the temporary absence of a strong magnetic field, the earth was left without its protective shield; as a consequence, cosmic-ray particles that were normally deflected by the magnetic field could shower through the atmosphere. The result may have been the destruction, mutation or even creation of species. Scientists know that such reversals occur every 500,000 to 1,000,000 years. But they do not know...
Western experts are reasonably sure that Soyuz 1, designed to re-enter the atmosphere and descend at a controlled attitude, had only one surface protected by a heat shield against the high temperatures of reentry. If Soyuz was indeed tumbling upon reentry, as many U.S. experts believe, its unshielded surfaces would also have been exposed to the direct frictional effects of the atmosphere. As these surfaces began to burn up, temperatures in the spacecraft cabin would quickly have reached fatal levels...
