It's a pleasure to welcome you on behalf of Rockwell International and the Science Center to this symposium. We're very happy to join with Dr. Ed VanReuth and Dr. Mike Buckley in sponsoring this symposium.

Nondestructive evaluation or nondestructive testing, as some of you would call it, is a fantastica lly important subject to us, both to the company and we believe as a country. We're performing a little experiment with NASA and the Soviet Union today, and that little program has .a lot of dependence on nondestructive evaluation.
