PAO said they resolved the problem and are recycling th count to T minus 5.  He didn't say when the count would be picked up, though.

New T-0 configured, but they aren't sharing/confirming/using it yet.

I wonder how a charred Delta IV would handle a T-0 abort ;)

Recycle is complete so we are holding at T-5 mins, how long can that hold be maintained?

Problem detected by the launch computer (TCSR?)

too early for TCSR

Seems to me a script starts running at T-5 (like ones I built for Ariane launches some years ago), and this hold was detected within the script (what ever it's name is); & my ? then is when does the TCSR come in and 'take over'?

TCSR comes in at about 8.5 seconds.

Ahh - the terminal sequencer.... Tks.....

I left my countdown book at work

You'd probably get a hernia carrying that sort of thing around Jim ;)

They did a flight readiness firing on the first Delta IV (293), there's a big fireball and a lot of black smoke when the engine shuts down.

That is indeed an interesting question on how they would handle something like that.  My bet - re-application of foam........

That's news for me, thank you!
Is there a video somewhere? Now you've tickled my curiosity.

There used to be a video on the Boeing site, can't find it now though. :( Maybe you can go through web.archive.org and find it?

A lot of the charring on that first flight was because of the FRF. At shutdown the flame clung to the vehicle.

Thank you, great link! That shutdown sure looks ugly, even though it must be designed for those conditions.
