We spent many thousands of hours during ESAS looking for any
solid rocket failure mode that would create a more difficult
escape environment than a liquid rocket; that team identified
one only which applies only when the solid rocket is in line
with and below the crew capsule. Despite much hand waving by
an Air Force employee, there were no identified failure modes
that created a more difficult escape environment when the
solids were side mounted.
Since SLS's SRBs have no thrust-termination device, I presume no such mechanism
was assumed in ESAS. Does that not make any escape more difficult than from a
liguid booster, where rapid thrust termination is easy?
