Three planes lost before they decided to test and inspect the craft and found it was a multitude of factors with one of them being the window shape.

Carved out to that waffle pattern to make them lighter.

They ran into a problem when they tried to make the inside corners of the waffle pattern to tight of a radius.
they ran into this same problem with passenger jet air craft back in the early 60’s. They made the windows look almost fully rectangular and that concentrated all the stresses into the sharp corners. The sheet metal skins started to stress fracture and rip at and in some cases the windows started to fall out of the planes.
After that they made the windows almost oval in shape removing sharp corners and directing stress around the windows.

During the first stress tests it was all those corners that took all the stress and many started to crack and after they all needed to be repaired and buttressed.

A problem that was noticed and fixed 50 years ago. But somehow with a billion dollars to spend they forgot this commonly known problem.

As I remember, the Apollo missions were 3 man crew and did not have too much of a payload out side of the crew and some rocks, those capsules did their mission well, I realize that when talking about space, that lightness is a priority except over safety of the crew.
