Apollo Command Module forward hatch

Summary

[edit]
Description
English: Apollo Command Module forward hatch: Flight spare from one of the later cancelled missions. Very rare; perhaps only two exist outside the flown spacecraft. And, I was told, there is no good video of their operation. So I took one to demonstrate unlatching.

Apollo ran on low pressure 100% oxygen. The thin-wall LM has an open vent in its top hatch during launch to transition from 1 atm to 0 pressure. After docking to the CM, the pressure equalization valve in the CM forward hatch was opened to allow oxygen to fill the LM through the similar valve in its hatch that was left open at launch.
