COLLAPSE OF TEXAS TOWER NO. 4 201 



Senator Stennis. I thought you added something about the collapse 

 of a pier. 



Mr. Brewer. I said 



Senator Stennis. I do not know just how you connected it to your 

 other testimony. 



Mr. Brewer. No. The thing we said about the collapse of the pier, 

 if the bracing beneath the water were nonexistent, let us suppose all 

 the pins fell out or all the braces broke so that none of the structures 

 were present, then we have the feeling from very limited calculations 

 that one of these legs would have collapsed; that is, would have 

 buckled, which would have allowed the whole tower to come down. 



Senator Stennis. Yes. 



Mr. Brewer. So obviously, since we know from our investigations 

 above the water that this bracing is ineffective mathematically, 

 something should be done to restore its effectiveness. 



Now, we have no way of knowing above the water whether this 

 bracing was ineffective merely because the pins were in large holes, 

 which is not very serious, or whether there were actual members that 

 were missing, so that you would have to refer then to the testimony 

 of the people who made the underwater inspection to determine just 

 what was wrong with the undersea structure. 



Our above-sea measurements indicated that it was totally ineffective. 

 That means it is either gone or loose. 



Senator Stennis. Well, that is a very impressive point. I wanted 

 to review it not just for the purpose of repetition but to be certain 

 that I understood you correctly. 



Based upon the instruments which made these recordings, your con- 

 clusion was that these braces down there, for some reason, were in- 

 effective ? 



Mr. Brewer. That is correct. 



Senator Stennis. You are not expessing an opinion on what the 

 reason was, because you did not go below water. Is that correct ? 



Mr. Brewer. That is right. We have no way of knowing that. 



Senator Stennis. Thank you, sir. 



Senator Saltonstall, do you have any questions? 



Senator Saltonstall. Thank you, Mr. Chairman; just two or three 

 questions, Mr. Brewer. 



Mr. Brewer, you were employed by the Air Force; is that correct? 



Mr. Brewer. Indirectly. We had a contract with the Hallicrafters 

 Corp. of Chicago who, in turn, have an Air Force contract, and this 

 was just a mechanism; the Hallicrafters Co. takes small contracts, 

 deals with small contractors, so the Air Force has an overall contract 

 with them which will pick up these small contracts. That was the 

 reason for doing this. 



Senator Saltonstall. And what company was responsible for the 

 radar and the instruments, and so on ? 



Mr. Brewer. Which company was that? 



Senator Saltonstall. What I am trying to get at is, you say you 

 were employed by the — — 



Mr. Brewer. Hallicrafters Co. 



Pena'^or Saltonstall. What company? 



Mr. Brewer. Hallicrafters, H-a-1-l-i-c-r-a-f-t-e-r-s. 



Senator Saltonstall. You were employed by tlie Hallicrafters 

 Co.?
