You'd think they'd re-consider liquid fuelled boosters at this point re the safety aspect.

How so? The CEV design places the liquid upper stage on top of the solid-rocket motor assembly.

And in terms of reliability... The solids are the safest boosters that exist!

[Pessimist]

If reliability means "once you light it, it will burn", you're right. I thought the inherent problem w/ solid fuel was also "once you light it, it will burn". There's no way to control or shut it down after its lit.

Is this not correct?
