‍HOLY COW! What a time we live in that in a span of 6 hours SpaceX has rolled out 16 raptors! Booster 4 will need 29 in total so we should be seeing 13 more the rest of the night to early morning! #FullSend

The rapid assembly of Starship, its Super Heavy booster, and the orbital launch complex sets up yet another high-stakes showdown between the FAA and SpaceX. The company is going to be ready to fly, but there's no clarity on when the FAA will complete its environmental review.

24. 24 Raptors have made an appearance this evening/morning. BN4 isn’t gonna be ground bound for long. 🚀🚀🚀

This one was RC65!

Well. This is concerning.

BN4 looks like it has a dent. I sure hope this is the sun playing games with us.

‍UPDATE:

Most people are saying that SpaceX has had dents like this in the past and it will be fine.

I think we’re okay cause SpaceX isn’t frantically trying to save the $100M+ of Raptors underneath or evacuate the area.

Now that said, the dent looks B-A-D in person. Really BAD

If you watch closely to the right, you can see the dent appearing.

‍A full set of 29 Raptors is currently installed in Booster 4. I did hear that they were likely going to use some dev engines for fit checks, so this may not be all of the flight engines yet.
