ECO Sensor info (-----)
These sensors were cherry picked (all sensors were nano-screened and ranked, then installed as needed from the best to worst). There was not criteria cut-off for an unacceptable sensor.
The box had some tin whisker work done, also.

Problem is believed to be orbiter electronics, not the LH2 ECO sensor (source).
Point sensor box?
That's what they are thinking.

Has a Lockheed Martin prankster hacked into NASA TV's closed caption?

Looks like they are going to push for 3/4 ECO LCC for launch today.

WOW!
Personaliy I would scrub, trubleshoot and try again tomorow...
Do we have any reasons for pusing a 3/4 ECO LCC today?

A lot of people are not happy about this, but there's a management meeting to provide rationale to go with a launch.

We're checking the second sensor failure note.
GNC-74 is the LCC (Launch Commit Criteria) for an Air Data Transducer Assembly Pressure Anomaly
and
MPS-22 is the LCC for the MPS LH2 Low Level Sensor Anomaly
I have not heard what the exact signature of the two IPRs were other than the ECO sensor indicated Wet in the Dry state...

I guess we will not have a real discussion in this live-update thread, but just my two cents: one cent says "Wow! Gee, we gonna fly!" -- the other cent says "That ECO stuff sure sounds funny. We better scrub. And we better lift that damn night launch rule..."

Looks like they are going to push for 3/4 ECO LCC for launch today.
But what good would a 3/4 ECO LLC do if both sensor #2 and #3 are having trouble (or if it's the electronics that controls them, so that you might get more than 1 wrong reading during launch)?
Or am I misunderstaning how things work here?
