It was the fly-by-wire software for the F-16. Fortunately,
this error was caught in simulation and no planes were actually
flipped.  For more info, you might want to look in the risks-digest
report database "http://catless.ncl.ac.uk/Risks".  The bug in question
can be found easly by searching on "equator".
