George:

NASA thinks that they may have an intermittent ground problem acerbated by
the cooling of the liquid fuel in the tank. Current rumor is they are
switching two of the four outside electronic units and if the problem
reoccurs they may allow flight with only three of the four redundant sensors
working. Intermittent problems can be a real bear to isolate but I would
think they would have a little better test equipment than a Simpson VOM!
:-) 
Maybe they could try the kaleidoscope troubleshooting methods that are now
so popular. Keep switching components until it works. Apparently the problem
only shows up when the tank is filled with the cold fuel. Maybe wiggling the
wires is also a good test. Probably related to the tide coming in and out.

Dave,

I watch very little TV, so there may (Certainly) be more to the story than I

understand.  I think from what little I know the problem is with a fuel 
gauge.  They were hoping (desperately) that they could get it working by 
wiggling the wires!!!  That brings up the question... if the gauge starts 
working and they find they are running low on fuel, Who is going to bring it

up to them?  :-(

The CA can wait, but Portland will run right on schedule... count on it! 
:-)  See you there.

George Willer
