Wow, that factory in the video looks really slapdash.  Think they'll ever amount to anything in ten years?  Oh, wait...

Amazing, isn't it, what we have watched happen here over the last decade?

And EM's net worth was heading below zero about then...  $15B-ish now.

You do realize that this is a 7 yr old video, right? And this was YEARS before the first fairing actually flew, and by that point it had changed a lot. According to people knowledgeable on this forum, the actual flying fairing (not that early prototype) is not the lightest fairing of its kind. It may be the cheapest, but not the lightest.

The point of posting the video wasn't to take Musk's 10-year-old superlatives as gospel. It's evidence that they are in fact using aerospace grade composites, contrary to the speculation that the fairing is heavier because of inexpensive, non-aerospace grade carbon fiber. It lends credence to the explanations (particularly Jim's) that the fairing is heavy for structural reasons (i.e. supporting the payload while horizontal/transitioning to vertical) rather than the use of cheap materials.

Might have helped if I added some of the follow-on discussion to the post I originally quoted:

I don't see any evidence they are using anything other than current state-of-the-art aerospace composites for the fairing.  Let's not pile speculation on speculation.
Of course, there is no evidence they are using state of the art aerospace composites either...unless you want to assume/speculate that they are....;-)
We know the original manufacturer of the fairings was doing current aerospace grade work.  You can speculate that SpaceX simplified or complexified things after they brought manufacturing in-house, but until they do a major fairing redesign Occam's razor would state they are still using something close to standard manufacturing practice for composites.

And SpaceX disclaims any craziness:
Quote
. The fairing is 13.1 meters (43 feet) high and 5.2 meters (17 feet) wide. It consists of an aluminum honeycomb core with carbon-fiber face sheets fabricated in two half-shells.
http://www.spacex.com/news/2013/04/12/fairing

Note: when I say "state-of-the-art" I mean, same as any other current manufacturer would use.  I'm not claiming super secret sauce or unicorn novelty.

It's possible that SpaceX did an about-face and switched materials in the intervening time, but it's certainly a data point in favor of state-of-the-art construction.

The NROL fairing has been added to the collection at the Spacehab building, in addition to a security fence  8)

The fairing appears largely intact, although there is a discontinuity near one of the potential parachute attachment points.

So are both halves from NROL-76 or is one from NROL-76 and the other from SES-10?

One per mission - so far only one half of the fairing has featured recovery hardware.

any of these recent pictures, in this thread, help with determining if this particular faring is set up of reuse capability?

It's a little suspicious that they never show the full inside of the near fairing half.  The far side fairing I think I can confidently say does not contain the recovery bits we've seen in video.

Yes, my point exactly.  If there is recovery hardware installed, it is on the near side.  Impossible to tell whether it's present or not from these photos.

I think the recovery half has traditionally been the side with the male latches around the seam. So here i believe we are getting a look inside. but I think the past in flight recovery photos showed two seperate internal plumbing raceways, which at firt glave looks like there is only one here?

And no apparent chute bags.

Could the stuff near the top be an area for 3 copv to be mounted? Maybe the fab shop made a reusable half but they later decided not to fit it out with all the plumbing.

After SES-10, Elon told Martin Halliwell that they recovered the half with the American Flag, not the SES logo (at 12:34 in the video below).

All of these recent encapsulation pictures show the inside of the flag fairing, not the logo fairing (of which we only see the outside).

So we should be able to see recovery hardware if it's installed.

Private company, they don't owe us a thing.  We are lucky to get the excellent coverage we do get.

EM is a showman, he has to hold onto somethings to reveal later.
Excited to be finally into the first Falcon Heavy flow, we are getting so close!

Great picture of our launch today.  Next time (April) they'll make sure Iridium NEXT logo on fairing pointed my way!

I'm not really sure how that's relevant. He's talking about how the on-base viewing areas look south towards the rocket, which means they see the flag half, not the logo half.

Maybe at this point theyre waiting on the bouncy castle before they try any more recoveries.

Possibly, but they've still got a lot to work to do if they're missing the landing zones by several miles. I think they might as well take these opportunities to refine their techniques.

If they are not recovering iridium's vandy fairing, perhaps the reason is that Go Searcher is on the east coast. That is, perhaps the recovery effort needs a bit of ground support, and it was not (yet?) worth duplicating or not (yet?) operational on the west coast.
