- Systems Engineering Division reported 49 design changes were requested in the crew compartment, 45 of which were acted upon. The two most serious problems were:
- stowage of the portable life support systems;
- and the crewmen's knees striking the main display console at impact.
- Structures and Mechanics Division reported a number of minor changes to the docking system, primarily to simplify crew transfer and operation of the hatch mechanisms.
- Crew Systems Division (CSD) engineers evaluated the compatibility of the space suit and MSC's new in- house helmet with the Block II spacecraft. CSD reported that the suits were sufficiently mobile and afforded adequate visibility; problems with the shoulders, experienced in early versions of the suit, had been solved; and while the three crewmen still quite literally rubbed elbows, this problem also had been alleviated and no longer hampered the crew's performance.
