TOWER Findings of the Reconnaissance party indicated that the existing 75-foot photo towers at Aniysanii and Coral Head were in fair condition and could be repaired to serve again for the forthcoming experiments. According to Supplement No. 1 to the Reconnaissance Report, it was intended to use ten photo towers, including these two. One tower was to be erected on Runit, one on Aomon, two towers for stereoscopic photography on Teiteiripuecit, one on Bokonaarappu, two on Piiraai, and one on the coral reef south of Rumit Island. Two spare towers, which had been procured for Operation Sandstone were in storage at the Atoll. These were checked carefully and found to be in good condition, and it was planned to use these on Runit and Aomon., The six new~75 foot towers were to be of a new design because they were to be placed much closer to the zero towers. (See Chapter 5.11 for a discussion of tower design.) Later, in July 1949, instructions were received to recondition the towers on Aniyaanii and Coral Head but that they would not be used for tests. Also, the spare towers which had been intended for use on Runit and Aomon were not used. Ultimately, six newly designed photo towers were used, two on Teiteiripucchi, two on Piiraai, one on Bokonaarappu, and one on the site southeast of Runit. In the course of planning of the photo towers, it was proposed to locate this last tower on Runit rather than build an artificial island. Site plans were revised accord- ingly, but when it was ascertained that this change would place the tower too close to the zero point, the tower was relocated to its originally planned position. 5-55
