Mistakes can be made in any kind of software
The new F-22 Raptors have apparently been hit by a software bug during their flight from Hawaii to Japan. People are speculating that this is due to crossing the International Date Line. If this is the problem, it’s likely to be the rollover from 180*W to E.
This isn’t the first time this has happened, from Risks Digest 3.44:
Since the F-16 is a fly-by-wire aircraft, the computer keeps the pilot from doing dumb things to himself. So if the pilot jerks hard over on the joystick, the computer will instruct the flight surfaces to make a nice and easy 4 or 5 G flip. But the plane can withstand a much higher flip than that. So when they were 'flying' the F-16 in simulation over the equator, the computer got confused and instantly flipped the plane over, killing the pilot [in simulation]. And since it can fly forever upside down, it woulddo so until it ran out of fuel.
