Of course you would. Believe me, the people responsible for flight
software would too. The problem is that it's not a trivial task to
design and produce rad-hard parts. You don't just whip up a special
version of a chip in a few months and stick it in a spacecraft. That's
why a rad-hard version of the 8086 is just now being discussed for use,
because has taken this long to produce it.
Personally, I'd rather see them using a SPARC :-)
