			==Checklist==

			The Earth/Post-Landing checklist begins at an altitude of 50,000 feet, when the main re-entry process is complete and it is now safe to enable the ELS.

			Normally the crew will rely on the automatic operation, but if events do not occur correctly at the specified altitude, they will take manual control instead.
