Margaret Hamilton, who led onboard software development for Apollo, reportedly died at ninety. The article recalls the overload-recovery design that operated during the Apollo 11 landing.

Prioritizing essential landing tasks during overload
According to Ars Technica, Hamilton died last week at 90. The report says she led the development of onboard software for NASA’s Apollo program and had designed a fail-safe for overloads: during the Apollo 11 lunar landing, the computer reportedly kept essential tasks while canceling lower-priority work.
The article describes Hamilton’s earlier leadership of Apollo flight-software development and her work on error prevention and fault tolerance.
