C++/FORTRAN77 FORTRAN77 allows use of a code base that has the bugs beaten out of it years ago. Aerodynamics doesn't change. Also older Engineers can still comfortably write new routines. C++ allows use of Qt4 and all that it offers. Graphics, networking, SQL, etc. Intel Linux compiler makes it simple to mix and match. Also to pass complex data structures back and forth. At one point we had the same programs compiled to run on SGI IRIX, Linux and Windows. #ifdef made it easy.
