Schedule pressure on a single flight, or series of flights, is not the

How many flights does it take until the program is, in fact, rushed?

======================================
The idea of lifting off on a single one of those SRBs
came into focus for me when I saw a proposal described
here in sci.space.policy, for a three-ton weight on
springs (surely with friction dampers too) to absorb
and damp the vibration. *Three tons of dumb steel* on
a spacecraft? !!? Somebody is spinning like Road
Runner up a wrong tree, and no Wiley Coyote in sight.
It sounds to me like a severe fault in upper level
management.
I haven't heard yet why those SRBs vibrate longitudinally
in liftoff. Is the burning rate of the solid fuel too
pressure sensitive?
