Default Falcon 9 anomaly not related to FTS

Poor Mookie. Still stuck on stupid (and detcord).

I would expect that, when you are so interested in finding the cause
of the mishap, you would follow other people's attempts as well.


I have followed SpaceX's efforts quite closely and Scott Manley. I don't know this person you cite. You didn't name them nor give any links. Their idea must have been eliminated by the logic of my search algorithms - since I eliminated anything outside the body of the rocket as the cause.

The helium sphere and detcord were early suspects for the reasons I've already stated. If it wasn't the FTS then its a big mystery as to why a helium sphere would fail like that. When the S-IVB-503 test detonated in 1967 due to helium sphere failure, it was due to poor welds. A composite over-wrapped helium tank doesn't have welds like that. So, the failure mode is unknown at the present time. Though the microscopic examination of the parts pretty much points to the helium spheres failing.

Musk himself hasn't ruled out sabotage.

So, its an ongoing investigation.
