I recall reading in the Rogers Comission report that, in addition to all of the
engines gimbaling to try to compensate for the right hand SRB's underthrust,
Challenger's rudder was also trying to steer to the left.  I also have a vague

launch, an act which he described as "making an old rocket pilot like me
nervous."
