There is an interesting article  in Discover Magazine (July) about the 
mirror for the HST, which was made by Perkin Elmer.  The story tells of how long and how many precautions they were required to take before they could
move the mirror after casting.

Several years back (1966) some engineers at Perkin Elmer dropped a 
$1 million mirror destined for some satellite.  NASA is trying to be very
careful this time.
