The CSM weight program was reviewed by James L. Bullard of MSC and D. Morgan of North American Aviation at a meeting in Houston.

The CM 011 projected weight was at its upper limit as designed by the earth-landing-system restraint, about 68 kilograms above the maximum weight used for mission planning. Data to revise the 011 specification to show a CM weight of 5,352 kilograms were being prepared.

CMs 012 and 014 would present definite weight problems. At the time the CM weight vs earth-landing system factors of safety relationships were investigated in the study of the possibility of shaving ablator material from the heatshield, a maximum weight of 5,296 kilograms was established for the manned spacecraft. Bullard had discussed the possibility of a higher CM weight with James M. Peacock of the Systems Engineering Division and the earth-landing-system subsystem manager but had received no definite reply. Bullard said it was imperative that a firm weight be established, above which the weight could not grow, before any weight reductions could be seriously considered. It appeared that 90 to 136 kilograms would have to be eliminated from the spacecraft, and that the reduction would have to be accomplished primarily by removing items.
