COLLAPSE OF TEXAS TOWER NO. 4 209 



motions were because there was no one wlio could think of a way 

 to measure it. 



So, because of my experience on tower No. 2, I was engaged to 

 measure the motion, so that the people could tell whether they were 

 a matter of an eighth of an inch or 8 feet, because speculations ran 

 in that whole spectrum. 



So our job was, and our responsibility was, not to design or to 

 pass on the design or to pass on the danger or anything else, but 

 simply to measure how much were the motions and, in conjunction 

 with measuring the motions, what were the stresses at the deck. 



This we did, and this was reported to the designers, who have a 

 far greater knowledge of the integrity and the considerations of this 

 tower than I do. 



Now, if someone had asked us to design the tower and to make a 

 stress analysis of the tower, that would be another matter. But 

 we were not asked to do that, and we were brought in after the tower 

 was built. 



Senator Symington. I understand that, and let me hasten to say 

 in no way am I criticizing anything you did or didn't do. As you 

 give your testimony, it appears that perhaps if they had taken your 

 advice for another look based on your calculations, maybe this could 

 have been avoided. 



It couldn't have been built right in the beginning. That couldn't 

 be possible, if by right is meant that the tower was supposed to 

 stand up. 



I have no further questions, Mr. Chairman, 



Senator Stennis. Thank you, Senator. 



Mr. Brewer, you have said now that you made a report and a recom- 

 mendation, and you were not called back to make a further test. 



Did you find your letter? 



Mr. Brewer. Yes. I can quote from this letter; it is dated June 

 16. It is to the Air Force, Cambridge Eesearch Center. ^ 



Senator Stennis. Well, do you mind if we just put it in the record? 



Mr. Brewer. All right ; just put it in the record. 



Senator Stennis. All right. You may read it and then we will 

 put it in the record in toto. 



Mr. Brew^er. I will iust read 



Senator Stennis. The pertinent parts. 



Mr. Bre^ver. I will just read this one paragraph, and I quote : 



Senator Stennis. Give the date, Mr. Brewer. 



Mr. Brewer. June 16, 1959 : 



I believe an engineering study should be made evaluating quantitatively the 

 several methods proposed for reducing tower motions. 



Then : 



I would like to suggest for your consideration that a task be organized to 

 make an engineering study of the various methods of TT-4 reinforcement, 

 together with a prediction of the excursion reduction due to this reinforcement. 



I also recommend that we reinstrument the platform again this coming winter 

 to determine whether or not the underwater reinforcements now being carried 

 out by the Navy have been effective in reducing tower excursions. 



Senator Stennis. All right, Mr. Reporter, put the entire letter in 

 at this point.
