"Play back—" Heard "my" voice talking to my co-husband at Mare Undarum; "I" sounded tense but calm. Mike had given him situation, had told him to prepare Operation Little David’s Sling, keep it on standby for full automatic. "I" had assured him that master computer would keep standby computer programmed, and shift would be made automatically if communication was broken. "I" also told him that he must take command and use own judgment if communication was lost and not restored after four hours—listen to Earthside radio and make up own mind.
