Oneiros: natazha: I am a bit concerned about the solid rocket motors' joints. They were only certified until Dec. 2021.

Joints?

Like the O rings?

I thought they changed the design so the expansion of lower elements helped to seal the joint rather than open it like the challenger disaster.

Or is there something else unstable about them?

I think the most unstable element at this point is the rocket manufacturer, Boeing. From the makers of the 777 jet failure, the 737 max, etc.

Boeing is a shell of their former self. I cannot see how this can end in success. I can't count the number of pushbacks or keep track of failure reasons at this point. A successful launch on the 14th would be less likely than winning Powerball, I expect.
