MSC concurred in North American's recommendation that the 27½ degrees hang angle during parachute descent be retained.

(Tests with one-tenth scale models of the CM indicated that, at the higher impact angles, excessive pressures would be exerted on the sidewalls of the vehicle.) Provisions for a "dual hang angle" were still in effect for Block I spacecraft up to airframe 017. Beginning with that number, the face sheets on the aft heatshield would be modified to conform to the 27½ degree impact angle.
