My friends still working the program are telling me they're having huge issues getting FAA Part 25 certification (which I'd predicted back when the program was launched). Getting Part 25 certification of a military airplane is the very definition of "non-valued added work" - and it's incredibly difficult and time consuming.
It seems that making something suitable for military use can make it incompatible with the FARs. Who would have known - oh wait, that would have been me, six years ago (and I was far from alone)...
Sometimes is sucks to be proven right.
