In fact, as someone who has worked on simulators for about 5 years, I
was so amused when I saw it yesterday, that I went on a hunt to find its
source. Thank goodness for alt.folklore.urban!

It turns out that:
  *  It had next to nothing to do with OO code reuse. MODSAF is a very
commonly used stand-alone entity generator. Every virtual sim networked
to a MODSAF simulator will have to map MODSAF (or DIS) model IDs to
their own limited set of visually-displayable models. It is quite common
in the simulator world to use (hack) this function to remap entities to
something completely different than what MODSAF thinks they are.

I can recall a similar situation on a trainer I worked on where we ended
up with 3 piles of rubble flying in formation for about 30 minutes while
we tried to track down the problem. The pilots amused themselves during
that time by pretenting they were Borg cubes. :-)

  *  The kangaroos didn't really fire stingers, they threw beach-balls.
