	If, for some reason, the Tower Jettison Motor was to fail, or if, in the event of an abort, the Launch Escape Motor did not fire, the Launch Escape Motor can be fired manually using the LES MOTOR FIRE push-button on Panel 1 ({{Panel label\|name=C}}). Note that on a real Saturn this would not fire the separation pyros, so if you pressed the switch while the CM is still attached to the Saturn stack, you would just give it a small amount of extra acceleration as the Launch Escape Motor fires without pulling the CM away from the stack. In Orbiter this will separate the LES from the CM at the same time.

This is used on every mission, either to jettison the tower from the Saturn in a normal launch, or to jettison the tower from the CM in an abort.

	Note that the Jettison Motor nozzles are angled relative to the center of gravity to ensure that the jettisoned LES follows a curved path away from the CM to avoid a later collision. Note also that when the LES is jettisoned after an abort, a cable attached to the LES will pull the [[Docking Probe]] away from the CM to allow the parachutes to deploy properly.

	The final motor is the Pitch Motor, which is used in some abort profiles to turn the CM so that the heat shield is correctly oriented for re-entry.		The final motor is the Pitch Motor, which is used in some abort profiles to turn the CM so that the heat shield is correctly oriented for re-entry.

	The function of the BPC is explained by its name. It's a simple cover fitted over the CM to protect it from atmospheric heating during the 'boost' phase of the mission from launch until the Saturn leaves the dense parts of the atmosphere, with a secondary function of protecting the CM against the ~~Abort~~ Motor exhaust in the event of an abort.

	While the BPC was essential in a real Saturn flight, in Orbiter it serves no function other than to prevent you using the parachutes while it is attached.
