You are not Batman, sadly. But that doesn't mean you can't act like Batman, at least some of the time. One way to do that? Launch a grappling hook 100 feet up using a gigantic pneumatic launcher.
Yes, Battelle's Tactical Air Initiated Launch System can fire a titanium grappling hook attached to a Kevlar line up to 100 feet up in the air and 60 feet away, hooking onto whatever it can hook its claws around. And it being pneumatic means it uses compressed air, which is nice and quiet, just like the Dark Knight himself.
Sure, it'll be on you to then climb that rope, but hey, Batman has got to stand out from you and me somehow, right?
