They cant seem to match launch cadence to ship progression. This will most certainly set them back a few more weeks beyond the end of this month.
Likely longer as this was the only test site for Starship and there will hopefully be an FAA investigation.
I guess how much of a setback this is will be determined by how much damage is there on the facilities and the nature of the cause of the explosion(do they need to re-work the next 6 already being assembled so it doesn't happen again?).
