I don't recall ever seeing those on the "rudders".

I seem to recall a Redstone flight that had a total loss of all Rudder control.
How do we know those ARE rudders and not ailerons or elevators?

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, AGITATION, CHAOS, TURMOIL, FIASCOS, AGGRAVATION, INSTIGATION, NUISANCE-ACTION, and HAVOC !
