I think I understand the reasoning behind open floor plans, but what's the point of having everyone in a single mega-room? It's not like the two people in opposite corners of the hangar will be able to communicate seamlessly just because they're in the same "room"; they'll have to walk over to one another just the same as they would if they had walls separating them.

(Of course being in the same room doesn't hurt in that respect either, but partitions have other advantages as well, e.g., aesthetics and noise.)
