I have seen flight control cable failures under high tensile load... especially during crashes... but nothing like this failure...
Failure obviously occurred under high tensile load... wire strands unwinding/splaying about... but the break appears almost straight across all the wires at one discrete location. This is going to be an interesting failure analysis...
The investigation into why a cable mysteriously broke on the Arecibo Observatory has begun
Officials at the Arecibo Observatory in Puerto Rico still don't know what caused a cable failure that severely damaged the facility's iconic radio telescope this week, forcing it to shut down temporarily.
On Monday (Aug. 10), an auxiliary cable supporting a platform that is suspended above the 1,000-foot-wide (300 meters) radio dish broke and crashed into the telescope's reflector panels, creating a gash in the dish measuring about 100 feet (30 m) long.
