The same Los Santos airport aerial staircase, but now it's towable! It's the same 3D, but modified to be a functional vehicle, the only thing added was the hitch so it wouldn't look weird like a ladder being towed through pure nothingness. Due to the fact that it is a map object not intended to be a vehicle, some imperfections can be seen, but just ignore it, as it is the same 3d as the airport's statistical stairs!
