@killbasa, вроде это трос был и он цепанул за какую-то ЛЭП внизу:
"I was working and I suddenly heard a loud noise from the nearby building. When I looked through the window, I noticed that the rope of the platform on which the workers usually stand while cleaning the windows got cut and hit the nearby power line. The entire happening was very scary and spine-chilling, The event continued until the worker slowly got into the nearby balcony."
