The 1994 crash of the Ariane 5 rocket is a textbook example of verification failure. A 64-bit floating-point number converting to a 16-bit integer caused an overflow. The software module (which was actually unnecessary after launch) was reused from Ariane 4 without proper verification under new flight conditions. Simulation and static analysis tools, had they been properly configured with the correct range constraints, would have flagged this conversion as unsafe. The lack of proper verification tools and methodology led to a loss of $370 million and a decade of scientific progress. Key Types of Verification Tools and Use Cases
