   Interesting its not worth the RISK OF LIFE to bring it back
but it is worth the RISK OF LIFE to attach a rocket to it to 
up burn it up in the atmosphere. I wonder if anybody has done
some sort of environmental study about the tradeoffs since the
mission itself and the rocket attached will add more pollution
to the air.
   Maybe the need to destroy is to destroy any evidence of other
errors and short cuts taken by managers and those that built it.
Maybe they want to make dam sure it burns up even at the RISK OF
LIFE to those on the mission to destroy it so it can't be used
as evidence. Just a thought but it does kind of go along with 
the thinking that one must not do anything that can leave physical
evidence to point to management and there friends.
