by rocket, i mean in the presidential office. my friends and i got it to launch after having 3 reels, and holding down square [PS3], also i have seen someone no clip to get up there, and they were standing right on the cat walk looking at the zombies. I would think if Treyarch did not want people to go up there, they would have some sort of proxy or barrier, around it, which there is not. An example of this, is the table when you start off on Five. There is no possible way to get on it (that i know of) because there is a barrier/ proxy.
noclip allows you to get passed barriers, hence no clipping mode which means you can't get stuck in an object or "touch" it.
