Apollo+40: Early EVA?

The original Apollo 11 flight plan had the crew enter a rest period for about four hours after landing and clearance to stay on the Moon. How they expected anybody to calm down and rest at that point is anybody's guess.

Before launch, Armstrong and Aldrin had planned to ask for an early EVA.

104:39:14 (CDR): "Our recommendation at this point is planning on an EVA, with your concurrence, starting at about 8 o'clock this evening, Houston time. That is about three hours from now."

104:39:40 (CAPCOM): "Tranquility Base, Houston. We thought about; we will support it. We're GO at that time."

In about four hours, man will set foot on the Moon!
