"John "Jack" Garman, a NASA engineer whose knowledge of the computer aboard Apollo 11 saved the historic first lunar landing from a last-minute abort, died on Tuesday (Sept. 20). He was 72."
"Garman's death came after a several year battle with bone marrow cancer, according to an email by his wife that was forwarded to the Johnson Space Center retiree community and then shared with collectSPACE."

Twenty-six-year-old guidance officer Steve Bales was a key flight control team member who kept his cool while the onboard computer in the lunar module sent out a series of alarms.
