Well, I wasn't going to answer, but...

Several months ago I and one or two other people ported and demonstrated a 
uniprocessor version of a high-fidelity fighter simulator written in Ada83 
to a distributed, multi-microprocessor VME target using the Ada95 Distributed 
Systems remote procedure calls *in less than three months*.  The effort
included integration with two Sun workstations running separate programs
for the out-the-window view and the cockpit repeater.  Both of those were
written in Ada83 as well, by third parties.  

Usually the effort to port a sim is more than the time it took to do everything, 
including the intergation with the third-party software.  

We even included aural cues for the missle launches and explosions when 
the pilot shoots down the bogies.  Lots of fun -- a considerable amount of 
"validation" is included in the tree months cited. :)

Good people, good software written in Ada83 and a good design for Ada95 
distributed programming made it possible.

Oh, it included interfacing to the stick and throttle hardware too (A/D and
discrete point interfacing).
