In fact, if the FAA comes back and says that they've got some environmental violations, it could be months before it's all worked out.

However, the optics of the most innovative space company in the world, with contracts for both NASA and the DOD that are relying on this thing, having to sit there with this monstrosity of a rocket on the pad "ready to go" as soon as the FAA approves it...

Yeah, you have to imagine the FAA is going to try and speed things up a bit.
Agreed, and ballsy as all get out. Love it.

"You can't build an almost 500 foot launch tower without approval!!"

"Well, we already did..."

LMAO

Yeah, pretty much. I 100% understand why people hate Elon, but there's no question that he's willing to be abrasive in order to get shit done.

Hell, it wouldn't surprise me if the raptors on the bottom of the thing right now aren't even fully connected. They just want it to look like the FAA is dragging them down.

Yeah, he mentioned needing to do a fit check between the booster and the orbital launch table a few days ago. I imagine once that clears they'll start running cryo checks and sequential static fires. I have no doubt they'll be ready to launch long before FAA approval.

Moves at a pretty good clip...

I figured SN20 and her tiles would for sure be the hold up, but they are moving quickly on that too...

The first part of Tim's interview with Elon is up. These are gonna be LONG, but I'm excited to watch.

That’s pretty cool. Can you post the other two when they come out? I won’t ever remember to look them up but will watch if posted here

In progress on the video, and it's definitely super dense, but it's fascinating to hear him tell about design decisions.

"Every design is wrong. It's just a matter of how wrong."

Regarding the grid fins not folding, he gave a really in depth description of his engineering philosophy. To oversimplify:
  1. Make your requirements less dumb.
  2. Try very hard to delete the part or process.
  3. Simplify and optimize.
  4. Accelerate cycle time.
  5. Automate.

Pretty interesting to hear him talk about it.

The grid fins aren't going to be folded in like with Falcon 9? What's the time he discusses?

It starts around 13:15, but it's a long, drawn out explanation. The gist is that the loss in drag isn't worth the weight of all of the stuff that would be required to fold them up and down.

Interesting. I wonder if that will hold.

Starliner delayed again. :(

Yeah, time will tell. This discussion was started by #2 in his engineering process. Try to delete the part, since no part is better than any part that can fail. I believe he said something to the effect of, "if you're not having to add 10% of the things you remove back in, you're not removing enough."

So definitely they could come back at some point, but for now, they're trying to do without.

So take your time, and get it right.
