Dear Gary,


I have used some time of flight techniques on a vessel in South America. Not
necessarily research, but I was sizing cracks from the head of the vessel
that were 3 feet long and about 75 % through wall. Not a difficult task.


I have train some of the UT personnel at Boeing at your facility in Creeping
waves, Tip Diffraction, etc. I am on the road and I will let you know the
name of the person that I remember.


Sincerely,


J. Mark Davis
