actually, the UGS was sitting in the deep end, and the clamps keeping the ICI plate from lifting were not original equipment, as far as I was told. They were removed later, and the evolution was completed. (I was there supporting the evolution within about 15 feet when it snapped. Thank God it snapped where it did, or it could have been much worse. The "house refuelers" both had their hands on the rigging guiding it when the upper rigging parted)
