Thanks to all for the replies...
My thinking though... is S1#1031 is an almost year old block ?3? stage...yes?
SO... while putting Ti fins on it and trying to burn it down on an ASDS try makes some sense...
It's just as likely to be surplus and headed for scrap as the Block 5's start crowding the barns...
I guess we will find out soon enough...

Headed for scrap after re-flight wear and tear is analyzed... got to get the booster back for that.
ASDS is my bet.

Here’s SES press release:
Echostar 105/SES-11 Shipped from Toulouse to the Cape for SpaceX Launch
Written on 20 Sep 2017
With 12 days to go until the NET, I have to think that either:
1. The satellite was already there, and the press release just is late, or...
2. SpaceX+SES have gotten much faster at integration than the SpaceX payload guide suggests, or...
3. October 2 isn't realistic.
Anyone have any idea which?

[Spaceflight Now] Launch operators expect minimal delays from Hurricane Irma
SES officials said the SES 11/EchoStar 105 satellite weathered the storm without damage inside a SpaceX-owned clean room in a hangar near pad 40. If ground crews can resume work on the satellite within a few days, the payload could still be ready for liftoff in early October.

10 days (Sept. 29) to SpaceX Falcon 9 (SES-11) Static Fire...at 39A. Oct. 2 launch, then all hands on deck to prep 39A TEL for Falcon Heavy.

Seems suggestive of move to SLC-40 even if followed by
You know I dare not call 40 until I see it on a schedule

There's a distinct possibility that SES required an expendable full performance launch for this launch.
I'd say its 50/50 between ASDS recovery and expendable for full performance.

I thought that SES-11/EchoStar 105 weighed 5,200 kilograms and Falcon 9's maximum payload to GTO while recovering the first stage was 5,500 kilograms.

That depends on which orbit SpaceX will target for the launch.
5,500 Kg is for recovery on a standard GTO-1800 m/s mission.
Target GTO-1600 m/s (or better) and recovery might not be possible.
That's what full performance means for a launch like that.

Cross-posting a re-post from the NROL-52 thread:
Re-posting some information re: time-proximate launches, originally from the TDRS-M thread.
Thank you again to Jim.
***
48 hours or less to re-configure the Eastern range.
Launches on October 5 and 7, both from KSC/Canaveral, are possible.
Re: TDRSS use/possible conflict of use as part of launch ops.
Atlas V and Delta IV use TDRSS; Falcon 9 does not.
NSF experts, please correct if I'm wrong:
1. Currently, it takes approximately 3 days to reconfigure the launch range between Canaveral/KSC launches. Correct?
2. Some, but not all United States launches use TDRSS during launch. Atlas V/Delta IV: yes; Falcon 9: no?
***
3. Launching TDRS-M from Canaveral on 8/10, followed by NROL-42 from Vandenberg, both on Atlas V's, is eminently do-able, yes?
4. Launching NROL-42 on Atlas V, from Vandenberg on 8/14, followed by launching Dragon, on Falcon 9, from KSC later on the same day--also possible? No interference between the launch assets?
5. Are there any personnel that will work 2, or all 3, of these launches?
Thank you in advance!
1. 48 or less
2. correct
3. yes, but not going to happen
4. yes
5. yes

I haven't done this in 14 months, but I'll be recording video of the launch of SES-11/EchoStar 105 from one of Embry-Riddle's observation decks instead of covering the whole thing from start to finish.
Should be a picturesque view given that the university is 48.22 miles (77.6 kilometers) away from LC-39A.

Since it's only a few days until flight, have we gotten any definitive word on whether SES-11 is going to be an ASDS recovery or full expendable?

It should be ASDS based on the mass (5200kg), and the FCC permit we think corresponds to this flight has ASDS landing. It's a similar mass to SES-10.

Also Elon says so.

And FWIW, per Musk's 48 hours, the current schedule actually points to 36 38 hour back-to-back landings if schedules hold. Weather for the rest of the week at KSC is looking rainy and somewhat stormy, so upper level winds may be a bit rowdy. We'll see.

Nit: Because of the time zone difference it's less than 38 hours

When will SpaceX post the webcast information?
