October 1991
New Scientist;10/26/91, Vol. 132 Issue 1792, p24
Reports that a team of German researchers from the Max Planck Institute for Chemistry have calculated the effect on the ozone layer of a fleet of supersonic transport planes at either an altitude of 22 kilometers or between 17 and 20 kilometers. Production of a substantial enhancement in the potential ozone destruction; Benefits of the implementation of the agreement to limit the release of chlorofluorocarbons.
