Arecibo Radio Telescope suffers catastrophic collapse. - SilverFang01 - 12-01-2020

A sad day for science and for Puerto Rico.

To be fair, from the assessments that they did when the one main cable failed, it's not surprising that it collapsed. And it definitely says it was a good idea that they looked to decommission rather than try to fix it; if they'd managed to get to starting repair work it would have fallen even sooner, I expect.
Anyone who was petitioning to save it even in light of engineers going, "it's not safe at all to repair it," is an idiot, even though the loss of the whole thing is sad and was avoidable.

Eh, multiple ways to interpret 'saving the radio telescope'. Dismantling it, salvaging what can be salvaged and rebuilding it saves the radio telescope's mission capabilities, for example.

Now with video.
Look at it go!

I watched Scott Manley's video about the collapse (before this video came out), and he was pretty much spot on about the sequence of events. One of the remaining cables let go, and the resulting shift of weight distribution finished off the remaining cables on that side one after another as the shifting caused the load to exceed their maximum capacity, and the dome even fell off during the initial swing.
In the up close drone footage at Tower 4... as the second cable starts to give, you watch all the paint strip right off the cable, leaving the steel completely exposed.

Scott Manley synchronized the two parts of the video now.

I never had a chance to visit the Observatory and now I'll never be able to.
