Not a good day for the reputation of hypergolic propulsion. Luckily many viewers tuned out right after splashdown!

(Pet peeve: there isn't an "a" in nitrogen tetroxide.)

There's no vehicle in near-term development that doesn't use it. Shuttle & Soyuz also used/use it.

Starship.

SpaceX CEO Elon Musk and President Gwynne Shotwell leave mission control after a round of applause

I'm sure that I speak for everyone when I say that the applause is echoed on this site!

Now, I do hope that SpaceX are reasonably transparent about the turn-around and we can enjoy a "C206/Endeavour Vehicle Refurbishment for Reflight Updates" thread

Congratulations on a flawless mission. The gap is finally over may there never be another gap.
Congrats to Bob and Doug on a safe return and to all the teams.

Also thanks to NSF teams for great coverage.

So now we can start speculating on the hypergol thing and just how serious it is?

We get some hints from GO Navigator taking 25 minutes to arrive. She was presumably stationed at the center of a predicted landing ellipse, and travels maybe 10kn (5 m/s)? So she was maybe 7.5 km away?

You never saw a NASA HMFIC passing out sparkling wine in Mission Control.

Wow. Kate Tice breaking up on the webcast concluding this coverage. Not cool, not what steely-eyed-missile people do.

Just kidding. Nice to see actual emotion, shows that they were all really invested in making this happen, no matter the position in the company.

SpaceX does not own the Gulf of Mexico.  Otherwise, I'm not sure what the laws are out there beyond the 12 mile limit, etc.

International waters.  NOMARS are advisory.  CG can discourage but not prohibit.  Not that I'm saying it's a good idea though.

I find it interesting that they can parachute a fairing into the net on the recovery ship but they can't get closer than 7.5 km to the dragon parachuting down. Is that a safety factor, or a speed difference in the ships or a little of both/neither?

The CG routinely does things like drug interdiction outside of COLREGS.
The issue here is nobody apparently thought anything would be needed. That was a mistake won't happen again.
Also if USCG doesn't want to do it US Navy can send a MST to do it as well.
