Chinese bridge builders use rockets to shoot 3,200-foot cables across a valley


A big head-scratcher when building a suspension bridge is how to get those suspension cables from one end of the divide to the other. In the past, helicopters and boats have been employed for this purpose — even kites — but Chinese engineers constructing the Siduhe Grand Bridge had another idea: rockets. They used precision rockets to send 3,200-foot-long cables over a valley, and enable the construction of a bridge that would be 2,132 feet above the ground — which could easily fit any skyscraper in America underneath with room to spare.
