Rocket looks in perfect shape. Awesome Spacex.

Is it just me or does it looks like there's some cracking under where the landing leg was on the left side of Elon's video?
https://twitter.com/elonmusk/status/679145544673923072
that's a wire, part of the landing leg assembly I assume
in the video, we hear some quite load noises. Perhaps some drilling bolts into concrete to secure the stage with?
Could also be a multitude of machinery, from generators to pumps. Plus, my guess is they don't want to bolt it down - on the barge it made sense, for the trip, but here I think they'll just get it horizontal, no bolts required. Just my opinion, though.
I agree on the "crack", though - it's lighter than the rocket skin on one side and darker on the other, looks like a protrusion rather than a break to me, so it's almost certainly a wire, especially with the squiggly shape.

True about the noise. If you pause the video at the start, you can actually see a yellow aircraft jack semi-hidden behind the leg, being moved up. I guess 4 of those will be moved below the hold-down points.

To big to be wires. Hydraulic or pneumatic line to the strut probably.

There are two edges of the X visible: a blue leg on the left and a grey leg on the right. So that landing leg is sitting pretty close to the center of the pad.

I think that's a different divert, intended to protect the mainland against an over-burn on reentry. So all through the aerodynamic flight, the stage is actively "pulling" land-ward. But still falling short. And then at L-30 when the engine lights up, they do the final divert. At least that's how I always imagined it, and in all the pictures so far, the landing streak is shallower than the launch streak.
But - if I look at the 5-pad layout they've made, it looks to me like in the future the "crash pad" will be the center pad, and the only divert will be from the center pad to the final (smaller) landing pad.
If you look at the "double streak" long exposure picture, it seems to show such a maneuver. The return streak looks shallower, as if it's walking the IIP from off shore to the pad.
Yes, but don't forget the rectilinear distortion in the wide angle lens. Something in the corner of such an image can look quite crooked and still be vertical in reality.
Agreed. Hence my hedge... but the difference is really noticeable, and the streaks are not THAT far from each other.
I also realize there's an angle change wrt the camera, irrespective of the lens effect.
Still though.
Here is another image, from SpaceX. It looks much more vertical from this point of view. It is coming in a bit from the side (the nearer streak is the landing), but it is hard to tell how much is from the trajectory and what is from a divert maneuver.
From the "pencil landing" graphic it looked like most/all of the divert was before the landing burn, ie done by grid fins.

Where did you get that picture, and are there more like it?? Awesome.

Or its intended for something big. Really big.

Congratulations for everyone. The video and photos at the landing site have added the human aspect of accomplishment. Yet, I'm surprised the personnel are really that close to the stage for safety.

Let's all remember that this great achievement wasn't a stunt, and wasn't just a development flight. It was an actual paying flight! This flight actually benefits us here on Earth by filling out ORBCOMM's next generation constellation, tracking our food and other shipping goods all over the Earth.
This ensures that we will have more and more such flights, and more ambitious ones, and more efficient ones. Capitalism, folks!

Yup, very many people. Many thought it was the stage blowing up!

What, evacuate? In our moment of triumph? I think you overestimate...

Elon said the plan is to static fire the returned stage at the Cape on pad 39A, then examine it for flight worthiness and save it for posterity.

Including Elon, initially, from his reported comments in the post-landing telecon.
Is there any link/recording to that telcon? Where was it on?
