Here we can see the attachment points for the solar arrays on the drunk... nice photos...

I think those are the attach points for the solar array "pontoon" covers, specifically. On the left side is the power and coolant loop capsule-to-trunk umbilical. Below that is a new, or modified GSE side-to-vehicle umbilical attach point on the trunk. An perhaps, colored navigation lights?

Yeah, the red/blue lights ;-) Haha... we will see...

There appears to be a whole lot of rivets on the trunk, too. Makes me wonder if this one is made of Al.

Okay, I downloaded the picture and took a closer look.  Everybody looks sober (no obvious signs of inebriation) -- so which one is the drunk, and why would you attach solar arrays to him?  ;)

There it is.  A real live spacecraft.  Michael Griffin's legacy!

Even a stopped watch shows the right time twice per day.  ;) The COTS program is certainly one of the brighter spots on his record.

I think I can make out the right hand window opening under the plastic sheet.

Not to be greedy, but it would be great to get a photo from the side with the hatch.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

That's the front hatch, not a window. (the hatch extends down past the blue thing jutting out from inside) The right side window would have been facing us right on from this angle. But this spacecraft has both side windows removed.

Looks like an MVac nozzle can be seen in the background.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

There's also an interstage visible on the right between the two structures.

JIMO would have been the first proper spaceship.

Several, in fact!

Also, there's a pretty extensive use of cherry-pickers and other lifts for the Dragon. I wonder if that will stay once production ramps up, or if they'll build a more permanent checkout structure...

I admire their low-tech approach with cranes and lifts. (And note the ladder sticking out of the CBM hatch) :)

I don't think it will change too much, unless they REALLY ramp up production rates. As it is right now they already have 7 Dragons in various stages of construction.

I would agree with Simon.  Platforms are static and can't hit the hardware plus you don't need a certification to operate from one.  Where is the air exchange unit for the personnel entering the capsule via the ladder?  It is a confined space.

Maybe its on the left side where the hatch is, the black box?

Air exchange looks like left behind of Dragon, blue hose going into Dragon there. I agree that they should change somewhen to fixed structures... BUT! It's nice to see that they first spend money to build the spacecraft and NOT using first the money to build the supporting structures.

As mentioned previously, the capsule hatch is open, and two hoses (blue and a thicker light grey) go into the hatch. Presumably that is for air exchange.

Unfortunately, it always seems to take an incident/tragedy for people to become safety-aware. Good catch Jim.

I can only assume you feel the same about Lockheed Martin's work environment for Orion:

Are they "half-assed" as well? Especially in the last picture where apparently it is setup for work inside the capsule *without* any visible air exchange equipment.  :)
