Other arguments have been posted on this forum not a long time ago: * Restrictions of TOFD - Frits Dijkstra 22:58:39 8/25/98 (1) * Re: Restrictions of TOFD - Jan Verkooijen 17:24:34 9/23/98 (0) In that Frits Dijkstra's wrote "...using one technique as a "safety net" for the other" I like this idea, especially for testing of safety components which we have in the aircraft, nuclear and chemical industries (our this month's sessions!).

It seems that software costs nothing, it can be easily copied with no costs! We must consider that development time is a big part of the manufacturing costs and manufacturer need a fair return of investment. It would be interesting to hear from other people they know about more specific applications for that PE + TOFD could be an excellent marriage.
