MSC Director of Flight Crew Operations Donald K. Slayton pointed out to ASPO Manager Joseph F. Shea that LM-to-CSM crew rescue was impossible. Slayton said
Slayton added that several spacecraft changes, additional training hardware for valid thermal testing, zero-g simulator demonstration, and crew training effort would be required to permit extravehicular crew rescue from LM to CSM. Until this total rescue capability was implemented, manned LM to CSM operations would constitute an unnecessary risk for the flight crew. References: 16 .
