Exact moment of Arecibo telescope collapse captured on video

The Arecibo Observatory's radio telescope, built in 1963, has reigned as the 'world's largest radio telescope' for over 50 years. The observatory has been active in numerous planetary observations, but due to two major accidents in 2020, it will be dismantled in November. At around 7:53 local time on December 1, 2020, before the details of this dismantling plan were decided, an accident occurred in which a receiver of over 900 tons suspended in the air fell and the primary mirror of the radio telescope was destroyed. bottom.
Arecibo Observatory's over 900 ton receiver falls and crushes the primary mirror-GIGAZINE
The video of the Arecibo Observatory after the accident was released by the general public and the media, but NSF has released a new video that captures the moment of the accident. It seems that the images at the moment of the collapse were taken with two cameras, the camera in the operation control center of the Arecibo Observatory and the camera of the drone.
The first footage was taken with a camera installed at the Operation Control Center of the Arecibo Observatory. Suspended in the air is the receiver for the radio telescope at Arecibo Observatory. The receiver weighed about 900 tons and was suspended 150 meters above the ground with 18 cables.
This receiver is suspended by multiple cables, but suddenly it sways when it is blown by the wind ...
The cable is broken. You can see that the cable extending to the left of the receiver is broken while blowing powder.
Since the cable extending to the right of the receiver is not broken, it falls like a pendulum ...

At the end, both the receiver and the cable disappeared from the screen.
From here, it will be the image of the drone that was shooting the tip of the tower fixing the cable.
Suddenly one of the cables was broken when I thought that something like smoke had risen from the part where the cable was fixed.
Then disconnect the remaining two cables.
When the drone operator hurriedly rotates the camera in the direction of the disappeared cable ...
You can see that the receiver has already fallen into the primary mirror.
Since it is a drone, I will continue to raise the altitude as it is, and the video ends with the whole picture of the Arecibo Observatory at the time of the accident.
'I think we were lucky. The drone operator saw the moment of the accident and succeeded in pointing the camera,' NSF program manager Ashley Saudeller said in a press conference. It is a coincidence that he succeeded in shooting the moment of the accident.
