Saw Alicia Murphy's Periscope and there was a big thing covered with tarp on the barge. Possibly octaweb/engines?
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

Probably similar to the Jason-3 debris, strongest parts (engines & inter-stage) survived.

Here's pictures of the pieces from Jason-3 for comparison

Anyone going to be down by the Port today for debris pics?

Could be most of the stage... someone just let the air out.

Engines/octoweb are still in the center of the target circle, which would put most of the horizontal stage on board.

Thanks for grabbing the snap.

Looks far worse than the Jason-3 core, in terms of any sort of octaweb salvage.

Looks surprisingly intact for a tip-over. Previously internal pressure blew chunks of the tank skin all over the place and shredded it pretty thoroughly. This looks more like it just laid down and collapsed under it's own weight. The flattened-out section looks like it's still attached to the thrust structure/motors, Just with the uppermost part of torn off and collapsed flat on the deck. Could there be a fast pressure vent set to dump the tank pressure at touchdown down to limit flying debris or something?

Yeah, that was probably what did it. I'd just assumed it was the result of something intentional. Almost better it could work out that way -  It's free, completely automatic and can't unintentionally vent the tank if the stage lands undamaged.*

*Because tanks with big holes punched in them are pretty much by definition damaged.  :P It's not a bug, It's an undocumented zero-mass feature!

Well, that's one stage that won't need refurbishing. :)

Not that I'd expect there to be anything more than a few dents, but I do hope the deck isn't too badly damaged.
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Sadly, I fear the interstage didn't make it on board. That all looks like crumpled tankage to me.

Would have been useful to salvage the log files from the stage.

Is there any hints that they managed to retrieve the interstage? I thought the white thing on the sat image was it, but now it looks more like that was a piece of LOX tank.

Florida Today is reporting that Port Canaveral is looking to charge SpaceX $15,000 per returned core. SpaceX isn't happy. As had been mentioned, rocket cores are not a new thing at Port Canaveral (Shuttle SRB's, ULA stages) so its hard to see this as anything other than a bit of money grab... http://www.floridatoday.com/story/tech/science/space/spacex/2016/06/20/spacex-may-face-port-canaveral-fee-booster-return/86135670/

They key sticking factor seems to be that the proposed port fee is 7x what anyone else pays
and the port isn't providing any special services or even the crane!

So they want to charge $500/ton for a 30-ton rocket stage 12' in diameter secured on 4 stands certainly spreading the load over a 20' square?   

Meanwhile for comparison, a single 20' Standard Cargo Container can hold 25-tons and wharfage is $28/ton.

18x does seem quite unrelated to the actual wear and tear on the port.

Elon Musk -- sighing -- "Okay, how much will it cost to build our own little port just off Complex 39 on Merritt Island?  And will NASA lease the beachfront for the purpose?"

Don't tell me, I know, you can't just dredge a port out of a beachfront... sigh...

Wouldn't surprise me that San Pedro and Brownsville will jump on the bandwagon will do the same (IMHO).

They're acting like it's gonna crush the wharf, but what do you know
the rocket weighs a little more than a cargo container and is legally transported on the road from coast to coast.

The value of the 1st stage is what $20-$30 Million.  The harbor wants to charge $15k to un-load it from the drone ship.  Is this really a fight that SpaceX wants to have?  Pay the damn fee and move onto more important things.
