Congrats SpaceX on another amazing and seemingly perfectly executed launch AND landing!
Keep up the amazing work you are doing! Can't wait to see the first CRS on a re-used core, FH Demo flying and many other bold moves into the future!

Where was that video shot from? Looks like a great place to watch a landing.

The sonic boom arrives 11 or 12 seconds before landing.
This is MUCH earlier than what was experienced at OSB-II, which is 10.5 miles (~55 kft)
12 seconds is ~14 kft, and if there was a 5 sec delay at the OSB-11 (just guessing) that makes it ~20 kft closer for a distance of ~35 kft or ~6 miles
Jetty park is ~ 5 miles from LC-1.  Rt-401 is about 6.5 miles.
For those that have watched, which does it look like?
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

One of the payloads being carried inside SpX-12 is Cuberider 2 from Australia. Our media probably went a little overboard on the importance of this payload!

Pretty fancy setup they used for that video!

How was someone allowed to be there?

LC-37 is twice as far from LZ-1 as the USAF station is... over 4 miles away.

I regret that I have but one Like to give to this video. Utterly fantastic tracking job! I watched the final burn through landing half a dozen times!

At 6:17 of the video, there was a little fire from the central engine for about 3 seconds. That was between the reentry burn and landing burn.

I believe that is just them running LOX through the engines for chilldown or to help avoid FOD.  Hot soot + LOX = Flames

Great footage during descent!  Check out the brief appearance of the vapor cone / Prandtl-Glauert singularity at the 6m45s point, and how it immediately collapses upon engine ignition.

Thanks guys!  That was my video, I guess I should post future videos to the forum as well.  I'm still working on improving the setup, including a proper scaffolding around my table to keep glare off my monitors and some improvements to the intelligence of the tracking algorithms.  I also plan to distribute the tracking software in the near future for anyone with a similar telescope.

HPE supercomputer is still crunching numbers in space after 340 days

You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. That's what being a spacefaring civilization is all about. It's about believing in the future and believing the future will be better than the past. And I can't think of anything more exciting than being out there among the stars.
