Video of the late collapse at the Arecibo Observatory , taken from two different perspective , show the dramatic moment when a main cable failed , causing the 900 - ton instrument weapons platform to fall onto the large radio beauty below .
The first of the two videos was taken from the Arecibo Observatory control condition room , where radio stargazer unremarkably do their work . The television camera was of late installed in this location to capture a collapse should it occur , Ashley Zauderer , program theater director for Arecibo Observatory at the National Science Foundation , say newsman today .

As the video show , the political platform did not come flat down . It was more of a swinging action , as a principal cable bust from one of the three support towers . The video also shows the tops of the towers breaking off , some of which measure over 60 feet in length , harmonise to John Abruzzo , carry off principal sum of Thornton Tomasetti , an engineering firm brought in to assess the situation follow the recent loser of two transmission line at the famous facility .
The collapse involved some “ very tearing and unpredicted demeanour , ” order Zauderer .
The second video is just as remarkable , as it was captured by an aeriform trailer . It just so happened that the lagger was being used to inspect the top of Tower 4 when one of three remaining main cables snapped . Looking at the telecasting , you may see three cables extend parallel to one another . A quaternary cable television should ’ve been there , but it failed sooner this month ( you could really see the chafe clay of the transmission line at top ) . Each cable consists of 170 wires , said Abruzzo . The middle of the three stay cables is the one that failed , trip a response that stimulate the entire complex body part to collapse . A fourth cablegram settle above the triad is used to sustain the catwalk , and is not a main cable television .
unbelievably , the drone operator was capable to turn the television camera around to seize an aerial view of the carnage below , including the go down platform , azimuth arm , Gregorian dome , cable , and catwalk . In the distance , the top of tower 12 can be hear topple down the hill to forget of the operations building .
No one was hurt during thiscatastrophic failure , the precise cause of which is still being determined . Zauderer said all grave debris fell within antecedently designated qualified geographical zone .

On a prescribed note , the nearby visitor ’s center did not corroborate any serious terms . From here , the priority continues to be safety , mitigating environmental effect , and finding ways to abide the stave at the facility and the masses of Puerto Rico , enjoin Zauderer . progress in 1963 , the radio stunner was recentlyslated for demolition , as repairs were deemed too dangerous .
