Just like 0008993 says it's a glitch thingy. Most stuff isn't reachable when not seen, but also not shown if you have you feet on it. Maybe it's the same bug with this one here.

I've also noticed that items atop the lockers in the barracks rooms are occasionally unreachable (particularly helmets). And VERY rarely items on the first bunk (I just ran into a pair of pants I couldn't grab).

Duplicate of #0000662 (Some spawned gear is unreachable).
