...supersonic transport plane (SST) will be proven unprofitable within a year, William T. Coleman, Secretary of Transportation, said last night...
...After a year, I think, the SST will be pulled out by the British and French," Coleman told about one hundred people in Science Center...
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...
