Should have used a multiple axis switch (or accelerometer) with a computer function that told whether the switch was in a correct state at any given time.

I bet the design engineers and those who signed off on the document are getting their beatings. -Adam Peter Johansson wrote: >>From the d'oh! department... > > >Genesis crash linked to upside-down design > >17:18 15 October 04 > >NewScientist.com news service > > >Sensors to detect deceleration on NASA's Genesis space capsule were >installed correctly but had been designed upside down, resulting in >the failure to deploy the capsules parachutes.
