This is what happens when you make a bet to an industrial engineering buddy you were competitive with at university. You just have to go through with it.

The valley is the Siduhe, in China's, Hubei province. And was made possible by launching rockets a kilometer across a gorge that you could fit the empire state building in and still have room to build some commission flats on top of it.

"Previous solutions have included: attaching the cable to a kite and flying it over (e.g. niagara falls suspension bridge), carrying one end by helicopter (e.g. akashi kaikyo bridge) and floating one end on a boat (e.g. brooklyn bridge). the brains behind the siduhe bridge decided to ignore all those options and break another record instead. they attached the 3200ft cables to rockets and accurately fired them over the valley, becoming the first people to do so."

After almost 4 years of doing so, here is some pics of the processes.
