INSTRUMENT GRANDSTANDS GO UP. Instru- 

 ments, the eyes of the Operation, were installed 

 on top of steel towers erected on various islands 

 surrounding the Bikini lagoon. Television cameras 

 mounted in these lofty grandstand seats were fo- 

 cussed on the target array and, when the tests 

 occurred, permitted scientists miles from Bikini to 

 witness what was going on at the test site. Still 

 and motion picture cameras were also berthed on 

 top of towers to make a permanent photographic 

 record of what occurred. Towers were assembled 

 on the ground and hoisted into place.
