I thought the Mars Observer had a different problem, as in the parts were
built by different companies that didn't communicate clearly, and that the
'finished' product wasn't tested as a unit--the problem happened something
like this--
the retro rockets were suppose to fire when the landing pads connected with
the surface--the sensors to detect the surface were built into the legs and
when the legs 'bounced' on the surface, it woud trigger the rockets into firing
but what actually happened was that the initial separation of whatever heat
shield in the atmosphere, which caused the legs to 'free themselves' also
caused the legs to 'bounce' (which wasn't factored into the scenario) thus
causing the rockets to fire whilst the whole unit was still high up in the
atmosphere.
At least, this is what I remember being the issue. I could have a faulty
remembery on this--it wouldn't be the first time ;)
