Took a quick drive around the harbor this morning. Long story short, nothing interesting enough to try and get pictures on a crappy iPhone camera. Mr Steven is back, all four arms appear to be attached and unchanged from previous photos. No evidence of any nets, bouncy castles, or fairing halves visible from public roads.

Maybe this was a dry-run to test everything without actually committing to a capture?
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

Or could just be a miss. A tangled line on the chute spiraling the fairing half into the drink.

Or the doc ock isn't complete in time (ie, no nets or bouncy castles) so this was a dry run.  Just like it's looking like JRtI was down for repairs, causing the "dry run" ASDS landing.

Or else my theory of a week ago was correct, ad this did have a bunch of fancy mass-y new recovery gear... but it didn't work right.

Maybe we'll get some word from SpaceX, maybe we'll never know.

If you follow the crew of Mr Steven and they head straight for a bar, that might be a useful piece of evidence of how things went.

That's kind of stalky and no one is advocating that anyone actually do that. :)

I haven't seen this posted here yet: on the SpaceX FB group Pauline Acalin posted a pic of Mr. Steven in Port with rigging across those 4 arms. What can the detectives here sleuth from this?

That's my guess too, doing everything except catching the fairing.

There is a set of lines that run from arm to arm, forming a square at the start of the top, straight section of the arms. There appear to be two guylines running from the two aft arms down to the deck. I don't see the same lines on the fore arms.

The central platform the 4 arms connect to looks big enough for a fairing.

What could work would a vertically-oriented bouncy castle (VBC) “wall” amidships, plus a horizontally-oriented BC (HBC) on each outrigger. Outriggers lay out nearly flat on water surface for capture. After a fairing is dropped on an HBC by a steerable parachute, outrigger is lifted and fairing slides or rolls against VBC. Outrigger goes nearly vertical to grip fairing in place between VBC and HBC. Rinse, repeat.

So you're thinking these are the support arms for a set of "bouncy castle walls" that funnel the faring(s) into the centre?

Line the walls and floor with bouncy castle walls. Parafoil releases the fairing right over the  funnel, allowing it to fall onto the bouncy floor.

To me inflatable structures seem quite a bit more hassle to operate and maintain than appropriately tensioned nets. It’s not clear to me how significant the benefit(s) of using inflatables?

As well as a castle, bouncy castles are a bit prone to winds. 

Nets are also common nautical fair!

Agreed.  The four arm structure, to me, says "non elastic web".

If there's controlled give to it, it's created by controlling the tension in four cables coming down from pulleys at the apexes using brake winches.

One interesting point is NEC Quest ahead of her. She has a large A Frame davit on her stern and a fairing sized enclosure on her stern. Is she used for Dragon recovery ops?
