Crew Systems Division completed evaluation of the three Block II space suits submitted by Hamilton Standard, David Clark, and International Latex.

Also, the contractor presented to MSC the results of drop tests with the LEM's support and restraint system.

North American technicians began installing a CM mockup aboard a KC-135 at Wright-Patterson Air Force Base. The structure would be used in a zero-g flight test program (scheduled to begin within a week) to evaluate the Block I space suit re mobility, crew performance, and interfaces with the couch and restraints and with the guidance and navigation station.
