Now, here's something to ponder over... Thanks!

Here's the answer to some of the musings we had in the CEV section a while back... Section 1.4.3 goes into the rationale for the CEV's shape "...The resulting Cycle 4 CM shape is a photographic scaling of the Apollo Command Module. The vehicle is 5.5 m in diameter and the CM has a sidewall angle of 32.5 degrees. The resulting CM pressurized volume is approximately 25 percent less than the Cycle 3 volume, but has almost three times the internal volume as compared to the Apollo Command Module. The CEV was ultimately designed for the EOR-LOR "1.5-launch solution" and volume reduction helps to reduce mass to that required for the mission. Figure 1-25 depicts how vehicle sidewall angle and diameter affect pressurized volume and the resulting design point for each cycle..."  They did consider a CEV with a wider top.
