I'm not sure for a machine in this size range. For rather larger machines (think the big bridge or gantry mills - Fidia, Brandtmann, etc.) they are very often two axis heads.
I think even the very largest DMG Duoblocks have rotary tables with a sort of "nutating" knuckle head - but while they get quite large, I don't think they are fidia large.
A really *KEY* question is what is the effective working envelope at A=90° - that is, how big a part can you mill the vertical sides of? They are listing this machine at 64x40, but how much of that is lost between the "hinge" and the end of the tool? And for a given part, how much do you care?
Note that rotary tables (like on my DMU) are kind of by force square symmetric - you get some kind of circular work area that takes up a square space. But the VR machines are all 40" Y x whatever length. So the VR-11's 120x40 layout would have to be, well, a 120" rotary table. Maybe not a great model if the part is something like a wing spar - pretty long and relatively narrow.
Seemed to me, from various visits to IMTS and scanning on the web, that aerospace folks do a lot of "profiler" work - meaning they want head tilt, but not as much 90° head tilt as you'd think - more like like applications where they mill out pockets in a curved shape, and all of the pockets have angled walls.
