In a Miami Herald article presenting "the case for the Concorde," S. Fred Singer-who had served in 1970-71 as chairman of an interagency task group to evaluate environmental effects of supersonic transports-pointed out that the effect of Concorde pollution would be completely swamped by other factors that had been shown to decrease atmospheric ozone-nitrogen fertilizers, carbon tetrachloride, and fluorocarbons. Banning the Concorde from the U.S. would not prevent it from depositing pollutants elsewhere; in any case, military planes flying in the stratosphere and subsonic planes pushing to higher altitudes to avoid traffic would produce the same pollution effect as the Concordes. Singer, now a professor of environmental sciences at U. of Va., called for more study of the effects of Freon and fertilizers and for' modification of the engines of future SSTs.
