I guess the fairing landed, but was not recovered. (sunk before they could get to it?)

Musk: Correction, not recovered, but it was directed to a landing area. Will have "bouncy" castle soon.

Aha! So it looks like my guess that they will try to land it on an inflated surface was correct.  8)

I was told by one of the fairing recovery engineers this morning the fairing was recovered.
"It was recovered and hoisted into the boat."
Confirmed they only experiment with one piece of the fairing at a time.
Problem, I was told, is that some of the 'chute lines used for steering broke.

This is the first time I have had anything close to first-hand information like this.

So Elon probably meant it wasn't recovered in the "we can reuse it" sense but it was recovered in the "we found it and retrieved it" sense

Gwynne Shotwell is speaking at the 33rd Space Symposium on Wednesday. Hopefully there'll be some more info then and at least a photo? Just time to get everything back to port and do some editing prior to the presentation.

Possible return of recovered fairing to port? (image re-attached for convenience)

The Go Searcher is back in port. #SpaceX is there a fairing or portion of under the tarps? Will be docked at SpaceX Barge Dock

The need to equip or obtain a boat with an A-Frame hoist on the rear like they use to launch ROV's or deep sea research subs. That will make fairing retrieval easier

Only if they need to crane out of the water, and they have said they don't want to get it wet.

Looks like quite a bit of damage! About right for a first try, though, and the real accomplishment is getting them to a pre-determined place where they could be recovered.

Needs more than an a-frame on the back of a support ship for that.

Do that in port. Just cinch it down with cross straps and leave the castle inflated (at least partly) to cushion it where it rests for transport.

That's assuming the bouncy castle is on the back of a ship. It could be floating on its own and just anchored or tethered to the support ship or ASDS.

How about towing a bouncy castle into the wind.

Fairing under parafoil (or stearable parachute) turns into the wind on landing leg.

Similar to landing on aircraft carrier.

Minimize relative horizontal motion at touchdown.

I've done a bit of paragliding in the past, and a steerable foil has fairly limited control available. Obviously as a glider you cannot increase speed or altitude using power, so you need to stay on the 'high side' all the way in.
I was taught to land by making a gentle curving approach towards my LZ. If I felt I was too high, widen the curve to increase the distance travelled. If I thought I was too low, tighten the curve.

I'm not going to say it's impossible to do this manoeuvre onto a moving target, but it kind of makes my head hurt thinking about how you would fly that. But of course the fairings won't be flown by a mere human.

Maybe it will be less like a bouncy castle and more like a big lilo, turned up at the sides and at one end.  Like a stylized catcher's mitt.  The fairing approaches from the more open end.

Fast catamarans to do the final catch.
What can a cat do on the water and what will a paragliding PLF be doing?
35 knots?
With ELV best efficiency was the paradigm. The new paradigm is reusable, good enough, and commonality of design.
Same engines. Design once. Same vehicle. Design once. Reusable. Build once.

Why not bouncing castle on boat in picture, looks big enough. Will need two boats.  At $3m a half fairing they can afford to charter another boat for a few days.

Eh .. i've done a few swoop landing competitions. Not that i  won a lot, but it's not that hard. A few sky gods i know have done landings in a back of a truck.
Plus, look up thread and read up on what JPADs are doing today fully autonomously.
