Completed in November 1963, the giant (its dish is/was 305 meters wide) Arecibo radio telescope of the Arecibo Observatory (near Arecibo, in Puerto Rico) suffered apparently irreparable damage on the early morning of December 1st, 2020.
On that day, indeed, the telescope’s instrument platform (a 900 tonnes juggernaut, like about a hundred fully loaded 5th Wheel Camper), suspended above the already previously partially damaged dish, crashed into it definitely completing the destruction job.
Here a full account and footage of what happened.
