..and so, if you want to decrease collision with Mr Murphy, then revise
the design for Justin Case...
Oh God! have mercy.
Justin Case A. Shuttle on launching pad, don't tell me that some
un-inspected and un-certified parts were included, and the system cannot
be refuelled because a no-return valve was assembled into piping the
wrong way, inspected and certified.
After that, and only after that! NASA speck specified one way valves to
have different diameter threads on "in" and "out" ends.
Justin Case B. Idiot-proof design in which a push button is positioned
behind a metal revolving plate with a hole in "zero" position so the
button can be pressed. The "newer, better, upgraded" idiot got a very
thin long screwdriver and succeeded to press the button in HV position.
QED.
Justin Case C. Old, very old, mobile logical circuitry for support of
avionics, few racks of eqipment on vehicle and another vehicle sporting
a 3-phase generator for powering it. The "smartie" responsible noticed
that the main power plug has some screws wobbling, disassembled it, put
everything back, tightened the screws and connected.
Result, IC's exploding with such force that they created holes in
adjacent prints.
On inspection we found that the ground connection was inserted into one
of the phases and one phase was grounded.
My favorite Justin Case D. Avionics inspection of military planes
system, the security IS verything as some of the equipment includes
various "nasties". So a _continuous_ wire is running between ALL parts
of the equipment to let the safety part to be able to check existance of
proper connection of all parts for powering the system.
Safety refuses to connect, gives us about a week of hair tearing till we
find on "desperate" "crazy" full disassembly, can you visualise this
with equipment distributed behind panels in all parts of the "bird" till
we found it. Properly produced and inspected, proofs in papers! cables
were connected (Mil-Speck multicontacts) male to male and the connecting
technician did not notice but worked with such force or impatience that
the pins were bent everywhich way.
I rest my case of Justin Case and ask the court to call Mr.Murphy for
his expert opinion.
Have fun
