Dictionary of Technical Terms for Aerospace Use

This volume attempts to define the meanings of selected terms in use in areas of activity of the National Aeronautics and Space Administration. The effort has been undertaken because exactness and precision are naturally most lacking in times of rapid language growth; and yet for scientists and engineers precision of meaning can have exceptional, even crucial, importance, as indeed it also can for contracting officers and management in general. But in one sense this book is almost certain to be imperfect. No set of definitions frozen in type can hope to capture the continuing change of living language.
