You will have to give me your meaning of 0
" experience," please.
3 Q.
Certainly.
10 Were you cwa,re.of, problems in cracking in that 11.
area experienced by Delaval, R4 engines in the field?

.A.
Yes, I was.

Was that problem of cracking recorded in 14 documents that.you saa?
15 A.-
In documents that-I' prepared.
id Q.
Mcw did you como to prepare those documentc?
17 A.
As a result of various field trips that I ned 18 nade. and. records -that I had made during those field trifs 19 and;in-the normal course of recording those field trips.
