Didn't most of the military-industrial complex drop Ada in favor of C or C++ as soon as the DoD dropped the requirement that critical software must be done in Ada?
AFAIU the JSF software is done in C++, there is (or at least used to be) some JSF coding guidelines document on Bjarne Stroustrups web page. Of course, blaming C++ for the JSF boondoggle is unfair, but still, one wonders whether it was wise of the DoD to allow C/C++...
