Paul Crutzen and associates at the National Oceanic and Atmospheric Administration (NOAA) and the National Center for Atmospheric Research (NCAR) have long theorized that the sun occasionally produces the same effect that SST foes charge would result from large-scale use of Concordes. As he explains it, high-energy protons from solar flares, or eruptions on the surface of the sun, are hurled through space to the earth. At lower latitudes, most of the protons are deflected by the earth's magnetic field. But near the poles, where the lines of the field bend toward the earth, the protons...
These results show the need for further research into the effects of technology on the ozone layer. Large solar flares occur infrequently, allowing the ozone layer time to be replenished by natural processes. But man's assaults on the ozone shield, in the form of SST flights, aerosol sprays and other chemicals, are continuous and could permanently deplete the layer...
...made no attempt to dodge the claims of the environmentalists, who led the fight that stopped the development in 1971 of an American SST by killing its federal financing. In his 61-page decision, the Secretary frankly admitted that the 100-passenger Concorde "will be noisier than existing subsonic aircraft, save arguably for the B-707 and DC-8 on landing, which [form] 27% of the U.S. commercial fleet." As for fears that the Concorde would pollute the air or change the climate, Coleman found no evidence of any significant danger...
Granting of limited service to the Concorde SST [Jan. 19] would be akin to planting a small bomb in Times Square to see if its effect were boon or bane...
Still, some U.S. airplane manufacturers hope that the Concorde gets the green light at U.S. airports. They feel that the start of Concorde service would spur interest in their own efforts to develop an economical, environmentally acceptable SST, which the U.S. could build and fly by the 1990s. Considering the fact that no one is really sure about the Concorde's adverse effects on the environment, many airline executives also note that it would simply be unfair-and inimical to good international relations-to keep...
