Moon Missions: Apollo 13 The Lunar Module

One hour before reentry, the life-saving Lunar Module was jettisoned. Before closing the hatch between the Lunar Module and Command Module, the crew removed switches, supports, and netting to give to the people at Grumman Aerospace, the Lunar Module’s manufacturer, to say thanks for saving their lives.

Then the Lunar Module was jettisoned, destined to burn up over the Pacific Ocean.

The life-saving Lunar Module Aquarius is jettisoned shortly before reentry. It reentered Earth's atmosphere over Fiji and burned up.
