Low asked Donald K. Slayton for comments on the subject. Slayton replied March 1 that "this item had also been a concern of the flight crews during the early design of the system." But he said: "The handle forces to actuate the abort sequence have been subjectively evaluated and are considered high enough to prevent inadvertent actuation. Additionally, the outboard rotation (counter clockwise) was chosen over an inboard rotation (clockwise) as being the more unnatural of the two motions. . . . Crew training for launch aborts in the Dynamic Crew Procedures Simulator has not shown this design to be a problem."
