This Month's Introduction
Welcome to NDTnet 1999!
As you may have noticed, we've started the new year off right with improved NDTnet navigation. The main page "" will stay almost static; from there you can access all departments as well as the each month new current issue page; that's where you are right now. We are also looking forward to seeing increased sponsor activity in this new Logo section on the top of this page - Read more about traffic and prices here.

Most of this month's issue focuses on NDT in aerospace, with papers submitted by PACNDT conference authors and selected independent authors. We also have reports on the PACNDT and DGZfP conferences. The latter one also features commentary on NDT Politics and the Internet.
