In the MoD level(first Splinter Cell), there's a section early on where you can acquire a healthpack and disposable pick. It's an easter egg of sorts, making you jump from beam to beam, but it isn't too difficult. Anyways, assuming you know where I'm talking about, there's also a hole in the roof right above you. Is it possible to actually get up there? I've tried a few times but haven't been able to.

I've tried many times to get there, opening at the top of the stairwell, but there's just too far a gap to be able to reach it. Probably there to 'explain' why those construction materials are lying around, LOL.
