Mutant Marsupials Take Up Arms Against Australian Air Force
The reuse of some object-oriented code has caused tactical headaches
for Australia's armed forces. As virtual reality simulators assume
larger roles in helicopter combat training, programmers have gone to
great lengths to increase the realism of their scenarios, including
detailed landscapes and in the case of the Northern Territory's
Operation Phoenix, herds of kangaroos (since disturbed animals might
well give away a helicopter's position).
The head of the Defense Science & Technology Organization's Land
Operations/Simulation division reportedly instructed developers to
model the local marsupials' movements and reactions to helicopters.
Being efficient programmers, they just re-appropriated some code
originally used to model infantry detachment reactions under the
same stimuli, changed the mapped icon from a soldier to a kangaroo,
and increased the figures' speed of movement.
Eager to demonstrate their flying skills for some visiting American
pilots, the hotshot Aussies "buzzed" the virtual kangaroos in low
flight during a simulation. The kangaroos scattered, as predicted,
and the visiting Americans nodded appreciatively ... then did a
double-take as the kangaroos reappeared from behind a hill and
launched a barrage of Stinger missiles at the helpless helicopter.
(Apparently the programmers had forgotten to remove THAT part of the
infantry coding.)
The embarrassed programmers learned to be careful when reusing
object-oriented code, and the Americans left with a newfound respect
for Australian wildlife. Simulator supervisors report that pilots
from that point onward have strictly avoided kangaroos, just as they
were meant to.
