COLLAPSE OF TEXAS TOWER NO. 4 203 



examinations of these motions, and stresses, have you any opinion as 

 to whether the original design Avas adequate and proper for the 



purpose 



Mr. Brewer. I wouldn't have any opinion on that. 



Senator Saltoxstall. You would have no opinion on that ? 



Mr. Brewer. No. The only opinion I would have is the one I gave, 

 which is that the subsea structure appeared to be totally ineffective, 

 and this was reported. 



You see, my primary responsibility was to measure how much it 

 moved from the radar standpoint. 



Senator Saltokstall. Would you repeat that, please ? 



Mr. Brewer. My primary responsibility was to measure how much 

 this tower moved back and forth and around and around because it 

 affected the accuracy of the search radar ; but, secondly, I did measure 

 the stresses and was asked to measure the stresses, which I did. 



Senator Saltonstall. We have had considerable testimony concern- 

 ing the use of pins as opposed to welded connections. In your opin- 

 ion, was it properly constructed ? 



Mr. Brewer. I never went underneath the water tf) look at any- 

 thing, and the only knovv^ledge I have of that is just talking to the 

 divers and talking to the Navy people, and we have transcripts of 

 that in our reports of these convei'sations. 



Senator Saltonstall. So that you have no opinion on the question 

 of pins versus welding, or the tolerances of the pins, and so' on ? 



Mr. Brewer. We have no direct knowledge of this. 



Senator Saltonstall. You have no direct knowledge of that. You 

 never made any underwater inspection ? 



Mr. Brewer. That is correct. We never went underwater. 



Senator Saltonstall. Did you approve of the strengthening above 

 the water, by the use of X-bracing as shown on the model in red ? 



Mr. Brewer. I think I have to go into that a little bit. I suggested 

 that would be a worthwhile avenue to investigate, putting X-bracing 

 above the water. But I said this is a suggestion. But that it should 

 be investigated from an engineering standpoint, first, to see whether 

 it would be actually helpful ; it was my opinion it would be helpful. 



So when you ask did I approve, I did not. I suggested that this 

 would be a worthwhile avenue to investigate. 



I was never asked to approve it, and I never made any measure- 

 ments on it. 



Senator Saltonstall. I see. 



So you took no responsibility for offering an opinion as to whether 

 this strengthenuig above the water, as shown on the model in the red, 

 was adequate or not ? 



Mr. Brewer. Well, my suggestion was that the X-bracing might 

 be added to reduce motion and not to necessarily strengthen the tower. 



But I did suggest that this should be looked into because it might 

 well have the opposite effect as far as strengthening the tower. So I 

 never made any drawings or calculations of anything. 



This was simply a suggestion I gave to the Navy people when we 

 were discussing the motions that I had made otherwise. 



Senator Saltonstall. You told Senator Stennis, if I heard it cor- 

 rectly, and I would like to repeat it because I thinli: it is very impor- 

 tant, you told him that the above-water inspection showed that the
