Did the rain birds work as expected? I didn't see much water coming out.
I was wondering the same thing. A little concerned that the pad suffered damage because of it. Hopefully it went as expected and it looked strange because it just looks differently on this pad.

That shot of the SpaceX logo scrolling upwards past the LUT... Remind you of anything? :p
USA! USA!
Question, why no rocketcam this launch?
They probably lost the signal for some time and the one in charge of the feed forgot (?) to change it until 1st stage sep.
BTW the rocket has the number "31" painted on its bottom.

It appear they do not come on full force until the clamps are released.

Is there any thing in the CRS contract that would prevent SpaceX from putting advertisement on it's rockets or Dragon Capsule?
As I was watching the array deployment I was thinking that wouldn't be a bad spot for Musk to put some advertisement for his solar panels since there is a significant amount of eyeballs watching.

Flyright is correct. You can see them kick on right as the clamps release. (Sorry for the poor image quality)

OK, maybe I haven't been reading up on the latest... but was anyone else freaked out as the count got to T-10sec and the strongback (or whatever this new one is called) was still next to the F9. The old one on previous launches pulled away by T-1:00 minute. This new one really didn't seem to separate until ignition. Would there be an abort if the motion was too slow? Anyway, just something that caught me totally off guard.

This was known. Pulls back 1.5° just before T-2:00, then "throwsback" at clamp release.

No. This is how the TEL operates at Pad-A.

That was by design with the new TE. This is the first time we've actually seen it, though.

Congrats on the launch. One thing that's also being somewhat wondered on the public side, it looked like the rainbirds only came online at T-0 and even then seemed to be quite low pressure. Is that just a visual misrepresentation or was there some issue with them?
Edit: and any clues as to what the two distinct object were that flew out of the rocket or close to it prior to entry burn?

At T+6min40sec, during its descent, the first stage passed very close to two large pieces that were descending at a much lower speed.
Were these the fairings under parachute by any chance?
No "big" fairings on Dragon missions.
Of course, you're right. But something big for sure, two large pieces at T+6min32sec precisely. Just replayed it.
Yes there was definitely something there, but it couldn't have been the fairings. Could it have been the small nose cone? It seems pretty far back all the way near KSC.
Nothing that was ejected during the flight would be anywhere near the stage, it would still be going ballistic, the boostback burn means the returning core is on a completely different trajectory.
Whatever it was it looks to have been flexible / irregular in shape (and two separate pieces). Very strange. And a bit concerning.
Strange. Hopefully there will be a comment later on what it was. I'm sure SpaceX will be on top of it.

I was expecting it but it still caught me off-guard. That was awesome!

There has been a lot of discussion about the new strongback in these forums and elsewhere. But if you missed those discussions, watching this launch would have been freaky for sure.
Those discussions talked about the risk/benefit of the new setup. In terms of your question, the consensus is that there could not be an abort if the motion is too slow. All available evidence seems to show that the quick throwback is triggered by the same action that releases the rocket for launch. And there is no abort when those clamps are released.

Maybe the stiffening rings from the second stage engine bell? Those are jettisoned right around ignition.

I agree with those who posted later. It must have been debris from the first stage, like ice or something. I don't think it's anything to worry about.

Did anyone notice flame on the TEL (maybe around S2 umbilical) right after liftoff? Did it retract as far and fast as expected?
