Schiaparelli landing investigation makes progress
>  the erroneous information generated an estimated altitude that was negative – that is, below ground level.Kind of sad to see that computers nowadays still lack what we call common sense.  I mean the machine received negative altimeter data but if it had been able to just look around, it could have seen that this data was erroneous.  Hell, considering the descent profile was carefully prepared, the computer should also have noticed that it was way too early to reach the ground and should have concluded that something was wrong with the altitude measure.
