liked the article, and I suspect that the EOR/LOR approach
using the Stick will be how NASA actually returns to the moon
(if it ever does). It seems unlikely to me that the big booster
will ever be funded because NASA will probably spend massive
gobs of unplanned money just getting the CEV and CLV flying.

Yeah, that seems likely, but I hate the Stick! The idea of launching
people on a single SRB just sounds stupid to me, the Stick looks like
an accident waiting to happen! Just my gut feeling.

Every space launch, whether fueled by liquid or solid
propellants, is an accident waiting to happen. If you
look hard at the data, shuttle SRBs actually have
demonstrated a very low failure rate compared to
comparable liquid boosters.

The observed failure rate of the SRB's is about the the same as liquid
propellant stages, around 1 in 200.
