Suggest it's easier to work on mechanical clearance and GSE issues when horizontal. Doesn't need to go back to the HIF because its still fully integrated. FWIW.

The webcast is showing a 24 hour scrub for SBIRS-GEO 4, so that probably pushes the static fire to Saturday at the earliest.

Test won't happen on Friday if this 24 hour scrub turnaround holds.

(Cape Canaveral Air Force Station, Fla., Jan. 18, 2018)– The launch of a United Launch Alliance Atlas V carrying the SBIRS GEO Flight 4 mission was scrubbed today due to a ground issue associated with the booster liquid oxygen system.
The launch is planned for Friday, Jan. 19, from Space Launch Complex-41 at Cape Canaveral Air Force Station. The forecast shows a 90 percent chance of favorable weather conditions for launch. The launch time is 7:48 p.m. ET.
Do we have any idea how late into the day the range can switch to FH should the Atlas team need more time?

I expected them to have rolled it back to the HIF, so if they didn't I'm a bit surprised. I agree that horizontal but outside isn't necessarily any more secure from debris than vertical.
How could rolling back to the HIF be any more protective from whatever Atlas holocaust be? The HIF isn't that "hardened", is it?

1 layer of metal and insulation (I think I've seen insulation in the pics of the hif?) is better than nothing, if it's a going concern. At that range any debris is probably slowed to terminal velocity, so the roof and walls could provide some protection.

If it went vertical again,(thought I saw that somewhere) that puts paid to the notion they were going to roll it in to the HIF, and supports the idea that it was for ease of tinkering.

So Atlas getting delayed pretty much killed the static fire for tomorrow, right?

I don't have any particular insight, but if ULA declared a longer than 24-hour delay sometime soon, maybe they could squeeze it in...

Also that in one Chris G's post.
Para-phasing.
The SpaceX HIF is designed to withstand a CAT 5 hurricane according to a NASA PIO. So the HIF is harden when compare to many of the older Cape buildings that can only withstand CAT 3 hurricanes (i.e. VAB).

Air Force said, based upon AFTS feature, they'd be ready to do 2 launches a day. should SpaceX demands it, so, I guess that would mean 12 hour readiness, may be.

For real? I thought the HIF was built super cheap and thus would be less hardened than the VAB.
But I guess they could've made it really cheap but with thicker steel.

Smaller, lower to the ground buildings have lower wind loads. It's comparatively cheap because it's essentially a cookie cutter warehouse design, as oppose to a 100% custom vertical integration facility.

That was specifically 2 F9 launches in single day. i.e. where they don't have anything to reconfigure between launches and it's just a matter of shift scheduling and rest periods, etc. It doesn't necessarily hold true for F9 & FH launching on the same day. And currently it certainly ISN'T true for launches from different providers, e.g. ULA and SpaceX.

Yeah, I think you are right. It also concerns 2 different launch sites and just thinking of the size of this monster I bet AF will be extremely meticulous on this one.

Just a FWIW - From some angles, the FH looks a lot like the early shuttle stacks with the white-painted ET.

We've been so eagerly waiting for the static fire, only to see it be postponed again and again. To calm the nerves I made a Falcon Heavy simulator: http://falconheavy.space
Wow. I've never seen such clickbait like this.
It won't even let me proceed to prop-load, static fire, or even launch!
That was the whole point.
I'm not surprised though. My fellow countrymen from the Dutch province of Friesland have an alternate sense of humor. But they do produce a rather fine Beerenburg.

Doesn't beat Half Life:Episode 3 (or Half Life 3) though.

Yes it does. And I'm just as excited about this launch as I was in the Spring of '81!
