Abstract

According to present knowledge, a significant decrease in the stratospheric ozone can take place in the future due to the action of nitrogen oxides emitted in the exhaust of supersonic commercial aircraft. This may have biological consequences. Although some estimates are given of the possible consequences of such air traffic, it is also shown that reliable predictions cannot be made before better knowledge about the stratosphere is obtained. A minimum requirement is that no large-scale supersonic operations be started at this time.
