After 57 Years, Formal Verification Uncovers Critical Bug in Apollo 11 Guidance Computer

Despite 57 years of intense scrutiny including emulation, academic analysis, and thousands of developer reviews, a critical resource leak in the Apollo Guidance Computer went undetected until formal specification analysis revealed it. This discovery demonstrates that traditional code review and emulation, while valuable, can miss subtle resource-management bugs in mission-critical systems. The use of behavioral specification language combined with AI analysis suggests a powerful new approach to detecting hidden vulnerabilities in complex, safety-critical software.
