Do we know whether these boosters are considered block 3 or block 4? or is that not a relevant category for the first FH?This launch is somewhat of a one-off with future FH's will be block 5. Is this expected to effect certification?

I thought Block 2 referred to the v1.1 config.

So this is finally clear? Zuma moves to 40 and there’s nothing left to do at 39-A but get this on the pad?
So following CRS13 ... 39A HIF is cleared of Zuma, then booster/US integration, and we see TE tests?

It'll likely be quite a challenge to track all 27 engine characteristics stepping through the cold flows, feed lines, cryogenic "effects", as we have chilled propellants (another first here, a clustered vehicle with them, sure to have surprises). Lots of little details to reconcile, building to ignition sequencing (outboard to inner? staggered shutdown? cavitation?).So likely a very tedious December/January, even if we see a roll-out so soon.
2 km/s is not a small number for a kerolox stage, hence why I'm pretty skeptical we'll be seeing this happen.
