so highly motivated or steely-nerved that 

 their nervousness has been kept under tight 

 control. 



An interesting insight was provided in a 

 conversation with Mr. F. D. Barnett of Perry 

 Submarine Builders. Mr. Barnett described a 

 particularly difficult dive in Long Island 

 Sound during which the vehicle he was pilot- 

 ing was virtually at the mercy of extremely 

 swift bottom currents. At one point in the 

 dive he was pinned against a large boulder 

 and had to inch his way upward along its 

 face in order to break the current's hold and 

 surface. Accompanying Mr. Barnett was an 

 individual who had never dived before, but 

 showed no signs whatsoever of nervousness 

 or panic. Discussing the dive after surfacing, 

 the passenger's self-control was explained 

 when he evidenced surprise in learning that 

 such events were not commonplace. Perhaps 

 "Ignorance is Bliss" was the answer in many 

 similar incidents. 



The BEN FRANKLIN drift mission is not 

 too revealing in this respect because all of 

 those on board, except one, were experienced 

 submersible divers and no stress or danger- 

 ous situations occurred during the entire 

 drift. While there were a few incidents of 

 minor irritability between the occupants, 

 there was never a close approximation to- 

 ward a potentially dangerous human rela- 

 tionship situation. This is all the more inter- 

 esting because the crew was not selected for 

 their compatibility with each other, and the 

 background of this multi-national group 

 (two-Swiss, one-English, three-American) 

 was quite diverse. No doubt, the fact that 

 this was a first-of-a-kind endeavor had much 

 to do with the crew's behavior. If, for exam- 

 ple, this had been the tenth or twentieth 

 such mission for this crew, the relationship 

 might not have been so compatible, but it 

 wasn't, and the knowledge that one's short- 

 comings as an "aquanaut" might be revealed 

 internationally on mass media had much to 

 do with getting along.
