There can be attitude transients caused by hydrodynamic effects of the

Polaris was acutely sensitive to this because of their need to perform
a roll maneuver immediately upon ignition.


Coincidentally, History Channel this morning ran a show about the ICBM
Race and included Polaris launch footage. That roll was damned
impressive!
