SpaceX is about launch IFT3 and during IFT2, the booster exploded probably due to sloshing and an engine having something block its fuel supply.
What has SpaceX changed to avoid fuel sloshing?
Officially we do not know, since SpaceX is not talking about it.
However, the kremlinologists in the crowd, who sit there with cameras 24/7 examining every weld and visible seam, have some theories.
Between the Ring Watchers and CSI: Starbase, NSF, and others (Apologies to those I missed) they come up with crazy theories that sometimes are even correct. Usually with amazing 3D models to prove their approach.
For this topic, Ryan Hansen Space, who does a lot of 3D Modelling the other uses has a suggested theory, based on the welds seen on Booster 10 after it was touched up.
Some amazing video so I embed the Tweet/X here since it is impossible to summarize easily. Anyone now how to embed just the X video if so, please edit in for me...
