[ARC5] failure modes

[gordon white]

   White's corollary:

    If you tow a race car to a race track, there is a direct 
relationshipbetween the distance towed to the likelihood of failure;

     The one part you thought you'd never need is the one that fails.

     If you bring everyconceivable spare part including a spare engine, 
injectors, magneto, rear axle, none of those well ever fail. The part 
you left home on the workbench, will. And you will be unable to borrow 
or steal it from another competitor, or to buy it locally.
