Yep, only true task is actually lowering/raising the cables for the super structure. I can't wait to see how they figure out the best way to do it. I mean lets face it, a cable the width of possibly the Empire State Building being lowered or raised into the atmosphere and anchored from space to Earth... possibly one of the next greatest feats Mankind will pull off. Then we'll see about asteroid mining!!!
SKY RULE #32: Do not not not not not not NOT crash into the sides of those skyscrapers. They will fall over and kill everyone in the entire world and we simply don't have the resources to put them back up.
