If they are not, why scrub the mission when they are faulty? (OK, so this time they were cracked) If they are needed - presumably to guard against dangerously high temperatures - then why fly without them? A further analysis in continuing to determine if 4 of the 5 flight control computers can also be eliminated :-) -- ------------------------------------------------------------------------------ Stuart Warmink, Whippany, NJ, USA | sw@cbnewsl.ATT.COM | Hi! ------------------------------------------------------------------------------
