Dramatic video shows collapse at iconic Arecibo Observatory One view, from a camera on the roof of the observatory's control center, showed the instrument platform crashing to Earth, along with the top 60 feet of two reinforced concrete cable support towers that were ripped away. Engineers were developing repair plans when one of the main 3-inch-wide support cables attached to the same tower unexpectedly snapped on November 6. Engineers were assessing how to carry out a controlled demolition when the third cable snapped, bringing down the instrument platform. Note that a number of individual wire strands of the M4-1 and M4-2 cables are noticeably broken at the beginning of this video. Less than two weeks after the announcement that the Arecibo Observatory in Puerto Rico would be permanently decommissioned, as fraying support cables accelerated the possibility of spectacular collapse, the telescope’s internal tensions exceeded their bounds. Newly released videos show how the telescope's 900-ton suspended platform crashed into the bowl-shaped dish below. While the dish itself only moved with Earth's rotation, the instrument platform featured a steerable receiver pallet that allowed astronomers to observe targets up to 40 degrees away from the telescope's vertical axis.
