A bit of a summary from L2, more to come:
SSV PIC resistance and S&A device verfications are complete.
PRSD LO2 and LH2 load began yesterday at 1452L and was completed at 1929L, Tuesday.
GN2 to air changeover was completed at 2026L.
SSME final preparations are underway and TSM securing to follow.
OMBUU demates and flight cap installation were complete.
Dock seal deflation completed.
Issues worked: During ECLSS switch configuration, when cabin relief valve B was cycled to Enable, proper talkback indication was not received. Cycled and no longer an issue.
Issues being worked include: SRB aft skirt purge temperature dropped -Troubleshooting began after PRSD loading, with engineering evaluation continuing. -

Would the SRB aft skirt temp. issue be a constraint for launch? -

No, as it's behaved since and during troubleshooting. So right now it's ok. If it started to play up again, then we'll see. Wouldn't worry about it whilst it's ok. -

Yes, that's typical. IIRC, the hood provides access for inspections and it may be lowered for fit checks and for that. (It's probably indicated in the S0007 timeline on L2.)QuoteFord Mustang - 6/2/2008 2:53 PM

Someone check the webcams at the pad, there's a problem (waiting for more).

I'm seeing on another list that a worker has fallen at Pad 39A. A medical helicopter is on the way in...

i am picking that up as well

Everyone pray he's ok. We're all checking.
Medical helicopter en route apparently, which I don't like the sound of, but could be a precaution. Don't want to speculate. -

Engineer was on a ladder and fell off and possibly had a significant injury, we're told. Helicopter will land on pad surface to pick him up. Doesn't appear it is stopping any other work.
