I did some googling to try to find out and only found a reference to "spin start support systems" when LC-40 was being prepared for F9 launches. Spin-up of pumps, or what?

However, no one figured to ask is there a Raptor powered second stage coming up anytime soon..

Raptor second stage will NEVER happen, plus they just test fired the first MODEL Raptor, the first full one will probably later this year. Why do people keep asking...I wish someone asked about FH's timeline (unless they did before I turned the stream on) and the future of Boca Chica

She also said she thinks they're still doing soil work in Boca Chica, but not much else.
I thought the big reveal - unless it is old news already - was that Red Dragon has been moved out from the 2018 to the 2020 window.
Engineers currently working on second stage right now. The fairing for the second stage GSE attachment point has been removed to provide access to the He piping system it seems. https://www.instagram.com/p/BQoKS-KDT72/?tagged=spacex

I'm somewhat confused about the crane and sling. The late-load photo pasted earlier in the thread shows a support sling from the TEL in the location of the sling from the crane. I'm hoping this is a one-shot work-around for some hardware bits that aren't finished yet.(edit) Upon reflection, I'm wondering if this is related to the 2nd stage work; maybe a safety issue since there are people working in a crush zone.
