The webcast is really dumbed down compared to previous ones. They seem to be aiming for a different audience today.

If the engine fails to light, it will crash on the pad. There is no better spot for it to happen, this is where all pieces can be recovered for investigation should it be necessary. Environmental cleanup is also much easier there.There is no such thing as falling "harmlessly into the ocean", if it is just by the beach. So I don't see them aiming there, but I've certainly been wrong before. 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.

anyone know if the telecon that just happened was recorded and where to find it?

This is the most beautiful picture I have seen in a long time.....SpaceX Twitter source. (Photo by Ben Cooper...got to give the guy props)

sonic boom of landing reached me as it landed - for a moment I thought it exploded!
I still can't quite believe it
I laughed so hard over the pencil gag.... Then went back into pending heart attack mode.
SpaceX just posted a piece on the background of tonight's launch and landing...http://www.spacex.com/news/2015/12/21/background-tonights-launch

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.

From Elon himself...
Check out this video shot from Merrit Island. Landing burn at 5:00 into the video PLUS a very pronounced sonic boom just after 6:00 (sonic boom arrives post landing)
