to tank or not tank.....

it appears theres a question of wether to run a test filling the tank,
to test the low fuel sensors, that were just replaced.

Although a test can show wether the sensor trouble has been fixed the
foam is believed to be damaged by filling the tank repeatedly. the
expansion and contraction can cause cracking leading to more foam loss
that will likely end the program forever

what a interesting catch 22.

another failure of the sensors will lead to long futher delays

more foam loss probably end the program forever

either way nasa loses....

I don't believe for a second that either, unless very bad would end the
program. However, I'd do a tanking test if I were there, as these sensors
are used widely, and the data would presumably prove once and for all
whether the problem is sensors, or something else.

I believe another serious foam loss flight will end the program, if for
no other reason than running out of time to fix it. now tanking test
will likely make foam loss worse...

another sensor trouble isnt a program ender unless it causes a
accident. sensor failure in flight can cause premature engine shutdown
or engine detonation and explosion if the engine ran dry, say because
of fuel leak.

sadly the shuttle has too many ways to get dead...

In article .com,
says...

Even more sadly, the same can't be said of your endlessly morose
postings.

Hey think what you like I predicted before columbia that we were going
to lose another orbiter . sadly I was right

I based this on the increasing number of close calls the program was
having.....
shuttle workers even some pad rats assured me everything was fine....

would everyone please read my original comments!

I clearly said

another sensor failure will cause long additional delays..............

more bad foam loss will likely kill the program..............

just what do you disagree with?
