But, given how SpaceX does things, why in the world are the words "Vertical Integration" used here?  As far as I know, Falcon 9 stages, first and second, are built horizontally...

Typo by whoever made the presentation slides probably.

Vertical integration as in built entirely in-house?
Which booster has the most soot? SpaceX booster launch history! (discussion)

Not exactly a "spotting", but Commercial Crew update shows B1051 being used for DM-1 mission, tanks are in vertical integration stage (getting COPVs installed).

That is an odd comment. As far as I was aware there is no vertical integration stage; everything is done horizontal.

I don't know that much about the manufacturing process, but when we get views of the Falcon production line there are always tanks off to the side in a vertical orientation (before the RP-1 and LOX tanks are joined).
And here is a picture.

Hi everyone,
I was wondering if we can except anything PR/fun oriented for this mission to the ISS? Something like a new starman ::)
Or maybe there will be some useful cargo?
And also, what kind of footage can we expect to see? (both DM1 & DM2)
As the Dragon 2 looks very futuristic, I hope they will live stream the interior during the launch : a good way to make space great again ;D

There will probably be a little bit of cargo on the uncrewed demo flights.

For ballast right?

It only makes sense to  make the most of the up and down mass.
Starship, Vulcan and Ariane 6 have all reached orbit.  New Glenn, well we are waiting!

Probably quite sober... wouldn't want to add things that would slow down NASA's processes... However I thought I heard there would be a test dummy, but can't search now, but a test dummy would make perfect sense.

A test dummy would be fun, but not NASA's style. It will certainly be instrumented, like the Orion test flight.

They could have an instrumented test dummy like the “Mannequin Skywalker”.

I wonder about putting a mannequin in the Dragon for DM 1 but unlike Starman, this one would have the suit fully pressurized and covered in sensors to check everything over while traveling to the ISS (the fact that SapceX didn't do that for the FH honestly surprised me, but that's for another discussion) ... Tho they've apparently been testing the heak out of these suits here on Earth so i'm not sure if that's entirely necessary...

While NASA will want some more normal things to bring aboard the Dragon on this mission, I bet SpaceX will be allowed to put something small and fun on board given that i'm sure there is plenty of margin for the mission... NASA did approve the big wheel of cheese for the first cargo Dragon after all...

I mean, if we're talking about utilization of DM-1/DM-2 for fun or otherwise, NASA is already studying the possibility of having DM-2 turn into operational-length crew transport missions (3-6 months berthed rather than a few weeks). No doubt that DM-1 will include some amount of provisional cargo, if only to simulate the mass of crew.

Whoever said NASA was consulted in the matter?  After all, that test didn't go anywhere near the ISS.

I guess some rodents are in order this time as a proof of the living conditions on board.
At least they will certainly have enough cheese.

Maybe in order to have real datas about the effect of the final splashdown on human body? Kind of multiple sensors as there is on crash-testing mannequin?

I'm not sure how valuable DM1 would be as a test for the suit, given it would not be exposed to vacuum at any point (out at least you would hope not)

Maybe to have a live ECLSS and com system check (using the Zond 'tape recorder with pre-recorded dialogue in the suit' trick)?

Maybe for fit checks and belt-buckling checks under microgravity? The ISS crew could give feedback on any unforeseen issues.
Also some feedback on how well it stores under microg, and to have spare parts, though I know each suit is unique to the astronaut wearing it, so this is unlikely.

I haven't been following this closely: is a mannequin/suit going on DM1 or is this just speculation of what if?

Crew Dragon is at @NASA’s Plum Brook Station testing facility in Ohio, home to the largest thermal vacuum chamber in the world, to demonstrate its capability to withstand the extreme temperatures and vacuum of space. Once complete, Crew Dragon will travel to Kennedy Space Center in Florida ahead of its first flight.
