Although, the article [0] does not say that literally, it sounds
like an integer overflow:
> After trawling through mountains of data, the European Space
> Agency said Wednesday that while much of the mission went
> according to plan, a computer that measured the rotation of the
> lander hit a maximum reading, knocking other calculations off
> track.
> That led the navigation system to think the lander was much
> lower than it was, causing its parachute and braking thrusters
> to be deployed prematurely.
> "The erroneous information generated an estimated altitude that
> was negative—that is, below ground level," the ESA said in a
> statement.
That is why we need CheckedInt, folks. Reminder End. ;)
