That was definitely a much faster flip than SpaceX have done in the past. They are getting very smooth at this stage return.

Noticed that too. They want to limit damage to the interstage by second stage ignition as much as possible.

Dear God, at one point I was asking myself: "is this real?" Hooray for tracking cameras!

It took only 12-14 secs from separation to start of boostback.

Stunning landing footage from that trackimg camera. I thought riding the stage all the way down was going to be the highlight of F9 landing coverage, but watching the stage come down that way made my jaw drop. Well done to SpaceX's tracking and production people.

It's a good job that the second stage trundled off stage left of screen before fairing separation consideration considering how clear the viewing was.

So glad I got up a little early to watch this one live. That tracking cam footage was just stunning  :).

Ok, it's official.  NSF loves the NRO!!  Only reason we get to see the video tracking the first stage all the way through return is because they're not supposed to show any of the 2nd stage video.  That was amazing!
Absolutely agree!  The morning light was just perfect for catching every little detail of the return flight. Well worth the very early rise on the west coast.  I've been wanting coverage like this ever since their first return attempt.

Mad props to the tracking camera crew.  Does anyone know if this is a NASA asset?

Now to rewatch that stream over and over again... :)

Staged 10 m/s faster than CRS-10, and 4 seconds earlier. Seems very likely to be an upgraded booster.

Entry burn is confirmed as 1 3 1. Center engine ignites, then outer two ignite, then outer two stop, then center engine extinguishes. Great to see. Apogee 162KM, so no question the stage is a space flown artifact. ;)

It's like a surfboard of fire...

Well worth the west coast early wake up. Well done spaceX, Elon.

This is why I am still hopeful about our planet and confident that Tesla is about to kick some serious end-of-fossil-fuel economy ASS!

Go Elon!!!

Wait, is that confirmation of successful orbit?  Or just that they got off the pad?  Huh.

The mission is "CLASSIFED".  Unless we suspect a sinister motive that adversely impacts the American people, speculation as to its purpose, size, etc is not in our nations interest. 

That said, WOW.  The video was spectacular.  I was also surprised at the frequency of the nitrogen thrusters.  Anyone have an idea about the quantity of Gn2 onboard?

Was it me or was the re-entry burn vectored sharply off to one side during the middle phase? I wonder why they would have done  that; to give asymmetric braking?
