 GEOG: Whilst on the way back to Earth, a view out of a window shows  the Moon with around 50% of the far side showing. Only a small  percentage of the far side should be visible at that point.  When flying over the Moon, Haise looks down at the surface and says  "Sea of Tranquillity", when the view out of the window does not show  the smooth plains of that area. The scene shown is a mountainous  area with a curving rille running though it; it is actually the  Apollo 15 landing site at Hadley Rille.
